When a suspicious death rocks The Sinclair, Manhattan's most exclusive residence, security supervisor Eden Wright and resident Liam Blackwood uncover The Ember Club—a secret society hiding deadly secrets within its walls.

Eden Wright thought she'd finally found a safe haven—a night security job at The Sinclair, Manhattan's most exclusive residential tower. Haunted by betrayal and loss from her military past, Eden is desperate for a fresh start and a chance to rebuild her shattered confidence.

But The Sinclair is anything but safe. When a resident dies under suspicious circumstances, Eden teams up with Liam Blackwood—a wealthy tech entrepreneur and Sinclair resident whose own sister supposedly jumped to her death from the building. As they dig deeper, Eden and Liam uncover the existence of The Ember Club, a centuries-old secret society whose hidden headquarters lies within The Sinclair's walls.

Now, as they peel back the layers of deception, they realize that privilege can conceal the darkest crimes—and that the building itself is at the heart of a deadly legacy. Some secrets are worth killing for, and The Sinclair's most dangerous residents will do anything to keep The Ember Club's secrets buried.
