The Collectors Books in Order

The Collectors is a two-book romantic suspense series built around a nasty idea: powerful people can turn a treasure hunt into a game, then make other people take all the risks. The villains are the C7, a secretive group of wealthy collectors who pursue rare historical objects and use blackmail, money, and threats to move their unwilling players around the board.

The series changes its central couple from book to book, but the C7 provides the continuing danger. These are not cozy hunts for antiques. The people caught in the group’s games are pushed to confront private mistakes, old fears, and secrets they would rather leave alone, all while racing to locate something that has been lost for centuries.

In Lovely, Dark, and Deep, biologist Gillian Campbell becomes a target after mentioning a family legend tied to a valuable Templar cross. Her search leads to a shipwreck off Nova Scotia and puts her alongside technical diver Shane Burke. Cold-water dives, a tight deadline, and threats to people they care about make the attraction between them one more complication in a very dangerous assignment.

The second book, Deadly, Calm, and Cold, moves to rural England and follows American graduate student Samantha Crowe. Her research into King John's missing crown jewels draws the attention of the C7, which means she needs help from Brody Parker, a man with his own reasons for keeping his past hidden. Their search is shaped by distrust, shifting loyalties, and the possibility that the people giving orders may not be working toward the same goal.

History is part of the fun here. Each book uses a real-world mystery or legendary lost object as the engine for a present-day thriller, without requiring readers to know the background in advance. The travel and research give the stories an adventure feel, while the C7's methods keep the stakes personal.

Start with Lovely, Dark, and Deep to see how the C7 works and how far its members will go to win. Deadly, Calm, and Cold has a new couple and a self-contained hunt, but it lands better after readers understand the rules, rivalries, and cruelty behind the collectors' games.
