Absolutely recommended. Hands down. These are my favourite series in no particular order. In order to make this list, the series has to have more than 3 books and they have to reside on my Keeper Shelf.
* The Black Dagger Brotherhood by J. R. Ward.
* The Guild Hunter Series by Nalini Singh.
* The Psy/Changeling Series also by Nalini Singh.
* The Maiden Lane series from Elizabeth Hoyt.
Did I miss any? Rats!
* The Rarest Blooms by Madeline Hunter!
Miss any now? Do you have a series you adore? Or one I should have included? Give me a shout! I love to find great new books!
