“Humberto the Bookworm Hamster explores the joys of reading and friendship.  Humberto’s gift of imagination will delight children as much as his kindness towards others will inspire them.” – Cheryl C. Malandrinos, The Kids Book Connection
Crash is now in Spanish!

Marcelo is thrilled when he gets a golden retriever puppy for his birthday, but now he faces one of the toughest jobs of his life, not only because owning a pet is a huge responsibility, but because he has to find the perfect name for it—and that’s hard!

"This very sweet book about Marcelo and his first puppy had me smiling all the way through. (And wishing I had a puppy of my own!)... Mayra touches on the responsibilities of owning a puppy while keeping it simple so even a very young child can understand both the love and work surrounding having a puppy... I definitely recommend this book for children - especially those who have a love of dogs. This short and sweet book will be the perfect present." --The Book Stacks

"Humberto the Bookworm Hamster is suggested for readers from 4 - 8. Mayra Calvani's text explores the joys of books, the fun of an active imagination, and the inspirational effect stories can have on our behavior. When Humberto chooses to help the animals who suffered from the flood, he does so in the best tradition of the storybook heros he admires... Kit Grady's illustrations are charming, positive, and full of expression. All in all, Humberto the Bookworm Hamster is a fun book with a heartwarming message delivered in a subtle way that is never preachy. This book should entertain kids through several readings." Vicky L. Smith, Amazon Reviewer

"Ms. Calvani has written a lovely story about learning what’s important in life. Ms. Grady’s illustrations capture the characters' personalities perfectly, down to the spectacles perched on Humberto’s nose. This is a great book to share with your little ones at bedtime or anytime they want to cuddle with you. Be prepared, parents, to read the story over and over again. I recommend Humberto, the Bookworm Hamster for children, parents, grandparents, animal lovers, and everyone who enjoys a fun read with a gentle message." --Beverly McClure, YA author

"Wonderful drawings in vibrant colors enhance the storyline. Parents and teachers can use this delightful picture book as a starting place to discuss important issues with children. Is Humberto doing too much reading?  Is he ignoring "real life" for the fantasy life of books?  What is the proper response when disaster hits? This is a book children will want to hear over and over." --Lila Guzman, Ph.D., children's author

"This is an adorable tale of friendship sure to delight young readers. I loved the story and also the cute illustrations. A fun read aloud. My eight-year-old also loved reading about Humberto and his love of books. A must add to any children's collection." Kim Baciella, YABooksCentral
