We literally stumbled across the writer Christine Warren, whom we had not heard of before — but we found her novel Born To Be Wild at a used book sale. Since 2003 Christine has written a slew of hot adult-oriented fantasy romance novels, usually involving a human getting wrapped up with a non-human shapeshifter of some sort. Her series include The Others (as human/animal shapeshifters call themselves), Gargoyles (no connection to the Disney series but it shares some ideas), and Alphaville (specifically werewolves). Her web page at Fantastafiction has a summary for each and every book, if you like your romance explicit and your lovers of a different species.
