Hughes, Alison. Kasey & Ivy.Victoria, BC: Orca Book Publishers, 2018
Through twenty-six letters to her friend Nina, twelve-year-old Kasey chronicles the often humorous observations and impressions of her unexpected, month-long stay in a geriatric ward for the treatment of a rare but treatable bone disease ("osteo-something-something-itis"). Kasey tries to make her life less dull by wearing her own nightgowns, surrounding herself with her favorite stuffies and developing an unusual exercise routine. Hospital food, insomnia and the germy communal bath are enduring sources of dread, but some new (and unexpected) friends make her life bearable.

Thompson, Kim. Eldritch Manor.Ontario, CA: Dundurn Group, 2012.
Are those cranky old folks at the retirement home really what they seem? Twelve-year-old Willa Fuller is convinced that the old folks in the shabby boarding house down the street are prisoners of their sinister landlady, Miss Trang. Only when Willa is hired on as housekeeper does she discover the truth, which is far more fascinating. Eldritch Manor is a retirement home for some very strange beings indeed.

Vrabel, Beth. The Reckless Club.Somerville, MA: Running Press Kids, 2018.
On the last day of middle school, five kids who couldn't be more different commit separate pranks, each sure they won't be caught and they can't get in trouble. They're wrong. As punishment, they each have to volunteer one beautiful summer day at Northbrook Retirement and Assisted Living Home, where they'll push creamed carrots into toothless mouths, perform the world's most pathetic skit in front of residents who won't remember it anyway, hold gnarled hands of peach fuzzed old ladies who relentlessly push hard candies, and somehow forge a bond with each other that has nothing to do with what they've done and everything to do with who they're becoming.
