Twisted Twenty-Six by Janet Evanovich

Grandma Mazur’s new husband didn’t even make it to the honeymoon before dropping dead — and now his shady business associates think Grandma has something valuable they want. They’re willing to do anything to get it back, even if it means putting a target on her back.

Stephanie Plum steps in to protect her grandmother, but between gangsters, mysterious keys, and the chaos of her on-again-off-again love life, she’s got more trouble than she can handle. Ranger and Morelli are both offering help — and heat — but only one can keep her alive long enough to solve the mystery.

Explosive, funny, and filled with heart-stopping suspense, Twisted Twenty-Six proves that in Trenton, danger and laughter go hand in hand.
