Boys of Beaufort: Book Four. Boys of Beaufort, #4

Two cryptic letters. A keypad code pressed into old metal. A staircase descending into darkness that has no bottom. Sean Henderson has spent four years at Beaufort surviving by staying invisible. Now he walks willingly into the Society's underground - into the chamber where fifteen figures stand in Beaufort blazers and rabbit masks - because the only way to destroy something from the outside is to first get inside it.
Liam Parker removes his mask and smiles, and Sean understands everything in the shape of that smile: the entitlement, the orchestration, the particular pleasure of someone who has never once been held accountable for anything. Liam knows what Sean is. He has been watching. He has found the one weakness Sean spent years building walls around. And Sean, without flinching, says Evan's name. He says it as a target.
He says it to survive. He says it knowing that if Evan ever hears it, there will be no explanation sufficient to survive the aftermath. Evan hears it. Boys of Beaufort - Book Four is the book where loyalty and love collide at full velocity, where every promise is tested against the worst possible evidence, and where the question is no longer who is behind the masks - but whether the people who love each other can still recognize each other through the damage.
The Society wanted to break them. It may have found a way.
