Silver in The Bone By Alexandra Bracken Book 1

Tamsin Lark has spent her life chasing legends, but none matter more than the one that might save her brother. Whispers of an Arthurian ring—powerful enough to break his curse—have begun to spread, drawing treasure‑hunters, sorcerers, and killers into a race she can’t afford to lose.

To stand a chance, Tamsin must team up with Emrys, her infuriatingly charming rival whose motives are as slippery as his smile. Their uneasy alliance pulls them from the hidden tunnels beneath Boston to the haunted ruins of Avalon, where ancient magic twists every shadow and danger waits in every corner.

But the closer they get to the ring, the more Tamsin realizes that some secrets were buried for a reason—and claiming its power may cost her far more than she ever imagined.
