Hell Storm by Rachel Jonas

To some, having the attention of four princes might be a dream come true, but for Corina, it means four times the trouble.
Escaping burning buildings, living off scraps, being hunted by vamps—those are storms she knows how to weather. It’s having the entire world observe as she and the Dynasty’s golden boys engage in a blood bond that has her shaken. For all she knows, it won’t even produce a cure for the mysterious blood sickness like they’re hoping, which could mean she’ll be put to death anyway.
And to make matters worse, as a side-effect of the bond, she finds herself falling for the very beasts she once pledged to remove from power by any means necessary.
Talk about a conflict of interest.
