“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.

          See You in the Cosmos is an inspiring and original book that moved me and made think more about real life situations such as not enough money to buy food, no father, far away brother and a depressed mother. Having to take care of himself Alex Petroski buys the food, cooks, cleans and has a day job to top it of. Alex is space obsessed and like his idol Carl Sagan wants to learn more about space and the cosmos and what life is outside of earth. Unfortunately this is not a one man job. Unable to launch his rocket at S.H.A.R.F. South-west high altitude festival and with a series of video recordings on his golden ipod which he plans to send into space fail. More adventures happens which then takes him to his long dead Dad which then take him to his Terra which isolates in a wild adventure were Alex learns about love, trust and family. I would recommend this for children aged 10+ because of the mature themes and problems. Over all i give this book 5/1-2 stars. Amazing first novel Jack Cheng.
