A hilarious cozy mystery from USA Today Bestselling author Shannon VanBergen.

Nikki and the Glock Grannies are finally taking a break—from crime, chaos, and community gossip. A relaxing cruise? What could go wrong?! Everything, apparently.

When a body turns up in the hallway outside of their cabin, the crew is quick to call it an unfortunate accident—just a tipsy tourist who couldn’t handle the buffet cocktails. But the Grannies have seen enough to know a cover-up when they smell one (and it’s not just the bad cruise shrimp). With limited clues, an uncooperative crew, and suspects on every deck, the Glock Grannies must navigate tight quarters, casino drama, and a side of sea-sickness. Can they crack the case before the ship docks—and the killer walks free?

Seas the Day is part of the Glock Grannies Cozy Mystery series. If you love clever mysteries, laugh-out-loud moments, and unforgettable characters, you’ll love this high-seas whodunit.
