Cody and the Fountain of Happiness by Tricia Sringstubb illustrated by Eliza Wheeler*

This book is whimsical yet realistic . . . perfect for older girl readers who need to develop stamina and/or who are reluctant readers.
Cody loves summer.  But this summer might prove to be challenging. . .her quiet brother is in love with Payton Underwood,  her brother's career goal is to be surgeon but he faints when dissecting a worm at "doctor camp", her mother is trying out for a promotion, and a neighbor's cat keeps escaping.  . .  .can Cody's optimism and effort redeem the challenging obstacles?
I liked this sentence from the book (describing Spencer's grandmother): "If she were a building, she'd be a cottage."
I also liked the book featured characters of different ethnicity, but race/ethnicity was not the main focus.
*Highly recommend.
