The Quitters Club (2026)
Jessica Strawser
"Can you change your life by quitting the thing that makes you unhappy? That's the central question of this heartfelt and poignant novel. When a group of friends makes a pact to leave behind the biggest problems in their lives, they think they're taking a step toward happiness. But quitting can have unintended consequences, and sometimes the things you abandon are what you need the most. I laughed AND cried."

I, Spy (2026)
L M Kemp
"Kendal Carter's life is about to get hella complicated. A former spy, she's been hiding out ever since her cover was blown and her lover was killed. But now her former colleagues have tracked her down and have asked her to complete one more mission-it's never one, is it? She doesn't feel like she has a choice, but how exactly is she going to do this with a four-year-old in tow? A fun look inside the shadow world of private spies and counter-measures, I spy a hit!"
