I would recommend Allison Leotta, a former federal sex crimes prosecutor. Her debut novel is THE LAW OF ATTRACTION, about a newly-minted US attorney named Anna Curtis. A great read
Fatal Destiny - a Grace deHaviland novel
Fairstein, Reich, McDermid, Grafton and Kellerman - then how about some great Australians -
PD Martin, Kathryn Fox, Kerry Greenwood, Lindy Cameron, Sydney Bauer, Robin Bowles, Alex Palmer, Katherine Howell, Alison Goodman, Angela Savage, Leigh Redhead, Tara Moss
and Gabrielle Lord.
