Joining a team of time-traveling commandos may not sound like a cushy gig, but at the moment Al's only alternative involves a closed casket. If he hopes to survive working for The Institute at the Beginning of Time, he'll need a crash course on temporal paradoxes, recursive causal loops, and the very real possibility of the multiverse folding in on itself like a poorly made origami giraffe. To prevent a cataclysm that threatens The Institute itself, Al must dive into the time stream alongside a short-tempered saint, a self-centered cyborg, and an embittered survivor of the climate apocalypse. They'll need to outwit a deadly cadre of rival time travelers-hopefully without stepping on any butterflies or becoming romantically involved with someone's grandmother.
