Sleuth Callie Aspen wants to light up the Fourth of July tea party by solving a celebrity's decades-old disappearance, but her digging results in more fireworks than she expects.

Last Christmas, Callie Aspen left her tour guide job and settled in Heart's Harbor, Maine. Now, she helps out at Book Tea, her great aunt's vintage tearoom, where each treat has a bookish clue. Though she's excited to start her new life, Callie worries she may regret having burned her bridges behind her. Fortunately, she finds immediate distraction in the preparations for a spectacular Fourth of July tea party, which will recreate key moments from the town's rich history.

Intrigued to learn that 1980s TV star Monica Walker was last seen in Heart's Harbor before she vanished—allegedly to elope—Callie probes the townsfolk for information. She's stunned when several locals share contradictory stories about the last day before Monica's disappearance. Did she intend to leave her hit TV series? Was she being stalked by her ex? And why is the newspaper editor who investigated the story at the time so anxious about the cold case heating up?

When one of the talkative townspeople turns up dead, Callie aims to catch the killer. But it's no picnic: Deputy Falk doesn't want her meddling, and the locals suddenly know more about the past than they'd been at liberty to admit. If Callie and the Book Tea crew can't crack the case, they'll pay a very steep price in Joy Avon's explosive second Tea and a Read mystery.
