Blood of the rose - Kate Pearce

Desperate to defeat King Richard III and gain the English crown, Henry Tudor made a pact with the Druids that bound him and his heirs to the Druids' deadly struggle against the Vampires. Ever since, the Llewellyns, an ancient Vampire-slaying family, have been in the permanent employ of the monarchy. When vampire slayer Rosalin Llewellyn had to join forces with her enemy Christopher Ellis to defeat a rogue vampire threatening Henry VIII, their alliance led to a surprising passion. Reunited after a year's separation, they now face a new threat that could destroy their happiness.
