She’s A Keeper (Prickle Island Zoo Book 1) by Ali K. Mulford

A swoon-worthy volunteer, a no-dating rule, and a family of meddlesome zookeepers who make chaos their main attraction. Lark Lachlan has rules—lots of them. As the ever-responsible zookeeper in her quirky family’s zoo, she’s mastered the art of locking up her heart. But when Logan Anderson, a charming New Zealander with a smile more dangerous than a loose tiger, shows up as the zoo’s new volunteer, Lark’s carefully constructed world starts to crumble. Logan is everything Lark swore to avoid: flirty, off-limits, and absolutely not a part of her meticulously crafted plans. And thanks to her no-dating-volunteers rule, their red-hot chemistry is forbidden territory. That is, until one reckless, heart-stopping kiss has her wondering if she should tear up her rule book. With nosy family members (and many inquisitive animals) stirring up trouble, Lark and Logan must navigate wild hijinks, simmering slow-burn tension, and feelings as messy as the zoo’s cleaning schedule. Can Lark keep her heart in check—or will Logan be the one to break through all her defenses? Packed with laugh-out-loud moments, steamy romance, and wild animal antics, She’s a Keeper is the romantic comedy that proves rules are meant to be broken—especially rules of the heart.
