Catherine Mann likewise just published her first single title, but her SIMs are great and just get better as you go along
for dark situations, can't beat Gennita Low :o
for sexy guys, Christina Skye -- she claims her heroes are SEALs but the plots are not very SEAL like but they are action packed and amusing
and last but definitely not least for wonderful hurt suffering heroes (mostly ex-CIA) and good plots, can't beat Gayle Wilson -- look for her two Harlequin Intrigue series "Men of Mystery" and "Phoenix Brotherhood" at the used bookstore, and she just published her third Mira single title suspense "Double Blind" -- great action, love her characters
