If you made a recording to be heard by the aliens who found the iPod, what would you record?For 11-year-old Alex Petroski, it's easy. He records everything. He records the story of how he travels to New Mexico to a rocket festival with his dog, Carl Sagan, and his rocket. He records finding out that a man with the same name and birthday as his dead father has an address in Las Vegas. He records eating at Johnny Rockets for the first time with his new friends, who are giving him a ride to find his dead father (who might not be dead!), and losing Carl Sagan in the wilds of Las Vegas, and discovering he has a half sister. He even records his own awful accident. Cheng delivers a sweet, soulful debut novel with a brilliant, refreshing structure. His characters manage to come alive through the "transcript" of Alex's iPod recording, an odd medium that sounds like it would be confusing but really works. Taking inspiration from the Voyager Golden Record released to space in 1977, Alex, who explains he has "light brown skin," records all the important moments of a journey that takes him from a family of two to a family of plenty. Riveting, inspiring, and sometimes hilarious. (Fiction. 10-14) Copyright Kirkus Reviews, used with permission.

Gr 4-6-Using only transcripts of podcast recordings to tell a story might be limiting for most narratives, but here it allows 11-year-old Alex Petroski's naïveté and essentially optimistic and ethical nature to come shining through as he tells of his road trip with his dog, Carl Sagan. The decision to travel to SHARF (Southwest High Altitude Rocket Festival), near Albuquerque, NM, is as matter-of-fact as his choice to address his posts to possible extraterrestrials, who he hopes will find his iPod and figure out how things work on Earth. Alex's mother is clearly less than competent, and his distant brother, Ronnie, lives in Los Angeles, which allows Alex to pursue his intense interest in space and rockets unsupervised. Things go awry from the start, but various helpful characters come to his rescue, enabling Alex to continue his journey away from Rockview, CO, and eventually return to the town. He's an intelligent, likable kid, and readers will enjoy following his journey as he learns who is in his corner when the chips are down. It is eventually revealed that his mother has a mental illness, which shines light on the workings of their relationships and explains how Alex has come to be so self-sufficient. VERDICT A smart read with some serious themes. Give to tweens who love unusual realistic fiction.-Carol A. Edwards, formerly at Denver Public Library © Copyright 2017.

Eleven-year-old Alex Petroski is from Rockview, Colorado, U.S.A., Planet Earth. He is recording sounds on his iPod to send into space, just like astronomer Carl Sagan did on his Voyager Golden Records (Alex admires Mr. Sagan so much that he named his dog after him). As he gets ready to attend a rocket festival in Albuquerque, Alex also records an audio journal of his life. Since his mom is not functional and his dad is dead, Alex travels by train solo with his dog. When Ancestry.com alerts him to a man with a name and birth date that match his father's, Alex determines to go to Las Vegas to search for him and ends up losing canine Carl Sagan. This book's strength is its exuberant and utterly believable first-person narrator: Alex is portrayed as intelligent and naive, irritating and endearing. But it's his earnestness that attracts a motley collection of adults who help when his mom goes missing. Good for both budding astronomers and fans of road trip books.--Young, Michelle Copyright 2016 Booklist

Alex, an 11 year-old boy who loves astronomy, makes a series of recordings to send into outer space in an effort to communicate with aliens. He plans to launch them using a rocket at the Southwest High-Altitude Rocket Festival in New Mexico. Leaving his mother, who is neglectful and bedridden due to depression, behind in Colorado, he heads to the festival with his dog, Carl Sagan. His trip results in new friends, clues about his long-dead father, and a reunion with his half-sister. The book is told solely through Alex's recordings, which makes it an ideal fit for audio. De Montebello is an excellent child actor who sounds completely natural as the innocent, earnest, curious protagonist; the other cast members-Michael Crouch, Jason Culp, Graham Halstead, and Brittany Pressley-are not quite as memorable. The audiobook effectively creates the illusion of spontaneous recordings with sound effects and background noise added in. This creative and unusual audiobook adds an extra dimension to the written work and brings the story to life in a way that perfectly matches the subject. Ages 10-up. A Dial hardcover.

Alex Petroski, the idiosyncratic 11-year-old narrator of Cheng's poignant and funny first novel, dutifully records his thoughts and adventures into an iPod, "so when intelligent beings millions of light-years away find it one day they'll know what Earth was like." The result is a propulsive stream-of-conscious dive into Alex's life as he sets off alone from Colorado with his dog, Carl Sagan (named after Alex's personal hero), to launch the iPod into space at the Southwest High-Altitude Rocket Festival in New Mexico. There, he encounters an eclectic cast of rocket enthusiasts and persuades two new adult friends, one of whom has taken a vow of silence, to take him to Las Vegas to track down his supposedly dead father. The trip continues as Alex meets his half-sister, resolves the mystery about his father, and travels on to Los Angeles to find his older brother. Details about his mother and her "quiet days," mentioned throughout, take on increasing importance, especially once Alex returns home. Alex's strong voice drives this compelling personal journey with resonant themes of family, friendship, and resilience. Ages 10-up. (Feb.) © Copyright PWxyz, LLC. All rights reserved.
