TIME TRAVEL FOR LOVE AND PROFIT

A teen genius learns the perils and pluses of time travel.

Nephele Weather wants to fix her freshman year. Abandoned by her best friend, Vera Knight, for the cool crowd and bullied by her classmates—for the hairiness imparted by her Greek heritage and being exceptionally good at math—Nephele decides not to move forward but to go back…in time. Eschewing a Whovian T.A.R.D.I.S. or Wellsian machine, prodigy Nephele creates Dirk Angus, her quantum-foam-manipulating phone app, only to discover that she’s reset but others are not; with each reiteration, Nephele redoes ninth grade but can’t win back Vera, as everyone ages except her. Tying herself and the universe in knots, Nephele learns about love and loss, discovering that she can’t change the past, but she could be warping the future. Lariviere revels in math and science, unabashedly celebrates science fiction and romance novels, and anchors the story in a realistic, comfortably cozy coastal Californian setting. The lack of catastrophic, explosion-riddled scenes, evil overlords, or alien invasions renders this a gentle, grounded read, reminiscent of A Wrinkle in Time. Most students read as White; math and science teacher Mrs. Saint Johnabelle, a mentor figure, reads as Black.

A heartwarming story of hacking high school through math.
