Skeleton Keepers, book 1: With Fire In Their BloodKat Delacorte2022

When sixteen-year-old Lilly arrives in Castello, she isn't impressed.

A secluded town in the Italian mountains is not where she saw her last years of high school playing out.

Divided for generations by a brutal clan-family war, the two halves of Castello are kept from destroying each other by the mysterious General, a leader determined to maintain order and 'purity'. . . whatever the cost.

Lilly falls in with the rebellious Liza, brooding Nico and sensitive Christian, and sparks begin to fly. But in a city where love can lead to ruin, Lilly isn't sure she can trust anyone -- not even herself.

And then she accidentally breaks Castello's most important rule: when the General's men come to test your blood, you'd better not be anything more than human...
