Long in the Tooth by Killian McRae

Why are centuries-old vampires always falling for high school girls? Wouldn’t they want someone closer their own age?

Cornelius Van Hoyk has been a member of the charmingly undead since 1869. Has he held a passing fancy for a target of his sanguine pursuits? Of course, but it’s been years. Today’s young women simply do not appeal. Youth is wasted on the young, they say, and his time is wasted on “#them.” But what’s to be done? A vampire must eat, and an attractive young man must pursue beautiful, malleable young women…
But when Cornelius meets his latest conquest’s grandmother, all bets are off. Dorothy Leigh is everything he ever wanted in a woman: intelligent, mature, witty… experienced. But convincing Dorothy to see him for the sesquicentennial man he is on the inside and not the buff and virile stud he appears on the outside will prove a challenge. How do you woo a woman who’s been around the block and knows every trick in the book?
By writing a new book, of course.
