The Mad, Bad Duke by Jennifer Ashley

This is a paranormal historical. The hero & heroine start out being under the influence of a love spell. Not to worry though - they figure it out right away and there are no tedious recriminations like you might expect. All in all, a very good story w/ interesting, great characters. Really liked the side story w/ Myn & Anastasia (but kinda wish they would have had a book to themselves. The Duke is from the country of Nvengaria & finds out he has latent shifter tendancies (he frequently takes the form of a panther - which I think is cool because what could be better? - hot guy & cool cat). This is actually book 2 of a series - once again I am not reading a series in order. TONS of steamy scenes.
