For Penny and Rio: The Locked Doghouse Mystery

“Penny and Rio, the lovable sibling sleuths are off on a backyard adventure with a new friend, Hobbes, the great Dane, to solve a mystery for the anxious mouse, Squeaky, who implores the dogs to retrieve an important treasure before it’s too late. Figuring out how to get to the treasure is not easy, especially with the sister dogs snapping insults at each other. What is the treasure? No one but Squeaky knows, and he’s not telling. By lending the worried mouse their helping paws, Penny and Rio discover that Squeaky’s important treasure is something that’s just as important to them. In this heartwarming tale, Swanson creates an entertaining plot with a well-developed cast of characters for independent readers, both boys and girls, who love mystery, adventure, and hanging out with friends.”                                                                                                                                                                                                                                Clara Gillow Clark, author of  Secrets of Greymoor Candlewick Press

Penny & Rio – The Locked Doghouse Mystery is very much a book about family values. It is sometimes a real challenge to teach youngsters complex concepts, but Jennifer Swanson certainly seems to have the skills. This second book confirms my theory that this author has a very illustrious career ahead of her. Many people think of children’s books as being easy to write, that is a fallacy, children’s books are notoriously difficult to do well. On a technical note, the book is printed in a nice friendly font, I am guessing Ariel and the point size is ideal for the beginning reader. This is a book that young people will get hours of enjoyment from, and parents will appreciate the educational value.

I was even excited about finding out what would happen next. The overall story is fun, entertaining, and teaches the importance of family history to your little one.”     Thearmywife.com,  Oct 2009 

 ”Penny & Rio: The Locked Doghouse Mystery” is a sequel to “Penny & Rio: The Mysterious Backyard Meeting,” 2009 Mom’s Choice Award winner and 2008 Royal Palm Literary Award winner. Penny and Rio are crime-fighting pair of doggy detectives, and they must solve the case of the Locked Doghouse Mystery. They are trying to help Squeaky the mouse who has belongings locked in the doghouse next door. Squeaky is afraid to get his things because Hobbes, a Great Dane, lives in the yard and may object to her passing freely through. Penny and io find that as usual, it takes lots of thinking and teamwork to solve problems and mysteries and help clients, but that is what they do best of all. “Penny & Rio” is colorfully illustrated and written in brief chapters that keep interest high and pages turning. “Penny & Rio” should appeal to children age 8 and up.   Midwest Book Review, November 2009

 Penny and Rio are at it again. Well, mostly Penny. The Locked Doghouse Mystery is another 5 chapter adventure. This time Squeaky the mouse has lost something very important to him. It was left in a doghouse that has been locked. How will he get in to retrieve his precious treasure? If your children love pets then they will love Penny & Rio.                                                                            Kristi Bernard, The National Writing Center for Children, Jan 2010

“Entertaining, Heartwarming and Educational!  Jennifer Swanson reached for the stars and succeeded in her sequel to “PENNY & RIO: The Mysterious Backyard Meeting.” She brings back the famous dog detectives, Penny & Rio, who are well-known for fighting crime, and mysteries. This delightful chapter book, packed with colorful illustrations will capture the heart of any reader, regardless of age… The priceless ‘Treasure’ that the author created was not only found in the doghouse, but in the heart of many young readers, who considered this book a ‘Treasure’ in itself. “PENNY & RIO: The Locked Doghouse Mystery” is as funny as Walt Disney’s CHICKEN LITTLE, and as amazing as THE POLAR EXPRESS, with Tom Hanks.”  Geri Ahearn Book Reviews

For Penny and Rio: The Mysterious Backyard Meeting

Penny & Rio: The Mysterious Backyard Meeting is a softcover children’s book featuring two canine friends who are diametric opposites. Penny is curious and adventurous, while her sister Rio likes to sleep most of the day. When Penny discovers that a cat, a groundhog, a squirrel, and an owl are using her backyard as a meeting place, she is determined to learn more about what is going on – while Rio is convinced that sleep is young people who are almost ready to graduate to chapter books, and an important underlying theme – that one should be responsible for one’s current pets and not abandon them to the city pound for a new pet – is also present in the cat’s tale. Highly recommended, especially for young dog lovers.

I like this book a great deal, it has been well crafted, and I think that parents will appreciate the care that has gone into its creation. From what I gather this is the foundation book for an entire series about Penny and Rio, I do hope that I have the opportunity to read the next installment. Great work Jennifer Swanson.

Lol! This is a great book. Penny steals the show and Rio is the winning ‘straight man.’ Not just a book about dogs with human characteristics – not at all. You can honestly tell these two dogs (real characters at that) really did behave this way and the story hooks you right in with both dogs’ unique characterizations. We are a pet family here and I know my son is going to love, love, love this because our pets have such endearing personalities, too. We can relate! Great job.This book is geared for readers aged 9-12, but younger listeners will love having Penny & Rio’s adventures read to them as well.

If your children love pets then they will love Penny & Rio. These two dogs are very funny. This story gives kids a pets point of view as to what makes them bark and take a lot of naps. This 5 chapter book is an enjoyable quick read.                                                           Kristi Bernard, The National Writing Center for Children, Jan 2010
