STEPHANIE LAURENS!! Stephanie Laurens has 2 series... The Cynster/s The Devil Bride is the First in the series, than all his rakes of brothers are tamed by strong willed determined in the Regency era, its wonderful.... She just started another series on the Bastion Club, again, same theme... I didnt think anyone would come close to capturing my attention like the Mallory's but the Cynster's definately do...
Love Julia Quinn's humor, also regency style, hers is the Bridgerton series, some may be out of print... WONDERFUL stong female characters, adorable male rogue's, and Julia's humor is great...
Jo Beverly has 2 series that I love...
