(4) 4-6 In their third book, eleven-year-old Masha can't wait to go to a dude ranch, but, thanks to her "evil genius" sister Sunny, the girls go to mathematics camp instead. Masha wishes her six-year-old sister would get lost, but when Sunny does run away, Masha predictably changes her mind. Mann successfully depicts a complex sibling relationship. Half-tone illustrations capture each scene's mood.

(4) 4-6 Illustrated by Jana Christy. Still recuperating from her evil-genius little sister's last experiment, eleven-year-old Masha (Sunny Sweet Is So Not Sorry) unknowingly becomes the subject of Sunny's latest, which involves red dye, falling into a grave, and public humiliation. Mann shrouds a lesson about accepting differences in over-the-top humor; fans of the unrelenting absurdity, enlivened in sweet black-and-white drawings, will hanker for the next experiment.

(4) 4-6 Illustrated by Jana Christy. When eleven-year-old Masha wakes up with plastic flowers glued to her head, she knows it's the work of an evil genius: her six-year-old sister, Sunny. This crazy experiment-gone-wrong is followed by a string of unbelievable antics (e.g., a cast for an unbroken arm). Although the sisters' experiences are over the top, readers will enjoy Masha's witty voice; black-and-white illustrations showcase the hijinks.
