Double the adventure continues in this stand-alone sequel to The Twinning Project (2012).
Plenty of back story updates previous readers and catches up new readers to the dilemmas of the first novel. The father of identical (and half-alien) twin brothers Eddie and Tom still remains the prisoner of evil Dr. Traum. Both Earths (the original, where Tom lives, and a second planet, created by aliens and running about 50 years behind in the year 1958, where Eddie lives, in the same New Jersey town) are on a course for destruction, but whether it will be the result of human negligence, government interference or alien demolition remains a mystery. When an alien with a penchant for quoting Mark Twain visits the boys on their respective Earth homes, Eddie and Tom begin a zany escapade to save both planets. Told in a variety of voices, including those of the boys’ loyal and diverse friends, who have issues of their own, the chapters capture modern and 1950s pop culture and history—which Eddie and Tom hope to exploit. Lipsyte doesn’t always give much detail along the way, but in this case it works, keeping the story light and uncomplicated for reluctant readers.
An agreeably quick-paced time-travel romp. (Science fiction. 10-14)
