A Connecticut Vampire in Queen Mary's Court — Ian Hall

Having spent eleven months working his way into the Royal Court in Tudor England, 21st century vampire Richard DeVere did not intend to give up his hard-won position without a fight.
But plans go awry…
When his nemesis, Baron Exeter, murders Richard's lover in 1502, the resultant time ‘shimmer' is strong enough to catapult Richard forward through time to his home in 21st century USA.
Determined to return to avenge Lady Jane's death, Richard plans to duplicate the circumstances of his first time-travel adventure, but for that he needs to enlist another vampire's assistance.
Enter Renaissance Festival groupie, Steve Fraser.
Within weeks, the plans are set and the friends spin successfully back in time
Arriving in Tudor England once again, Richard finds himself embroiled in a civil war, and must swiftly choose one side or the other.
With his lust for vengeance curtailed because of the conflict, Richard must work himself into the heart of the tumultuous Tudor dynasty once again.
But in a world where wooden arrows and stakes are the norm, nothing is ever easy…
"A Connecticut Vampire in Queen Mary's Court" is the second in the "Connecticut vampire" series.
