“I haven't read anything that has moved me this much since Wonder.” —Jennifer Niven, author of All the Bright Places

A space-obsessed boy and his dog, Carl Sagan, take a journey toward family, love, hope, and awe in this funny and moving novel for fans of Counting by 7s, Walk Two Moons, and The Curious Incident of the Dog in the Night-Time.

11-year-old Alex Petroski loves space and rockets, his mom, his brother, and his dog Carl Sagan—named for his hero, the real-life astronomer. All he wants is to launch his golden iPod into space the way Carl Sagan (the man, not the dog) launched his Golden Record on the Voyager spacecraft in 1977. From Colorado to New Mexico, Las Vegas to L.A., Alex records a journey on his iPod to show other lifeforms what life on earth, his earth, is like. But his destination keeps changing. And the funny, lost, remarkable people he meets along the way can only partially prepare him for the secrets he’ll uncover—from the truth about his long-dead dad to the fact that, for a kid with a troubled mom and a mostly not-around brother, he has way more family than he ever knew.

Jack Cheng’s debut is full of joy, optimism, determination, and unbelievable heart. To read the first page is to fall in love with Alex and his view of our big, beautiful, complicated world. To read the last is to know he and his story will stay with you a long, long time.

          I just finished reading this book, and it’s great! All eleven year-old Alex Petroski wants to do is to launch his golden IPod into space. He goes to SHARF, to try to launch his rocket, but fails. Then he goes to find his ‘maybe’ dad. He makes loads of friends along the way, including his half-sister Terra, Zed, and Steve, and Nathan, and all the other people at SHARF. I would highly recommend this book to kids 9+. Thanks for reading my book review!

            This book is awesome! It is full of suspense (in my opinion) and it is highly, highly recommended. Anyone who reads this will probably see the world differently, at least that is what happen to m before I even finished the book.
