“Hobbs is in great form here, combining his love of the outdoors and extreme sports with the fantastic element of an invader from space. The slow revelation of how Brady’s body is being transformed is mysterious and compelling-the pace moves along as swiftly as gliding on two wheels down the Iron Mountain Road into Keystone. The sense of place is powerful, with bits of lore about the region making the reader feel immersed in the story and its setting, and the characterizations are especially strong in Brady and Quinn-two teens the reader really wants to know.” - Voice of Youth Advocates (VOYA)
“Setting is always central in Hobbs’s books, and this time he’s chosen the Black Hills of South Dakota as his backdrop. As fans would expect, he artfully weaves the human and natural history of the region into the story. As they might not expect, he amps up the outdoorsy action by tossing some sci-fi into the mix…. Offering something to tantalize nearly every boyish taste, this title is a great choice for reluctant readers.” - School Library Journal
