When a treasure hunt leads to deadly plunder, it's up to glass shop owner Savannah Webb and her trusty investigative posse to map out the true motives of a killer . . .
It's the dog days of summer in St. Petersburg, Florida, and Webb's Glass Shop proprietor Savannah Webb has an eco-friendly plan to help locals escape the heat—a recyclable bottle-crafting workshop taught by reticent store manager Amanda Blake. Turns out, the class is a bigger smash than expected, thanks in part to a pair of staggeringly old bottles brought in by snorkeler Martin Lane . . .
Linked to a storied pirate shipwreck, the relics definitely pique Savannah's interest. But intrigue turns to shock when Martin's lifeless body washes ashore the next morning, another glass artifact tucked in his dive bag. With cell phone records connecting Amanda to the drowning, Savannah must voyage through unchartered territory to exonerate her colleague and capture the twisted criminal behind Martin's death . . .
