YA/paranormal adventure in the vein of books I love, like _Harriet the Spy_. April and June Bliss are sucked into their elder cousin Arlene's troubles when Arlene runs away to escape a teen BootCamp and leaves her majickal journal with June. Hopping an Amtrak train to Chicago, the girls flee from Arlene's evil coven--which is now after April's math talent to sell it-& into the battle. Brainy romp.
