Amazon just announced Thomas & Mercer, a new thriller-focused imprint:

Five bestselling and critically acclaimed authors will be the first novelists published under the Thomas & Mercer imprint. John Rector (Already Gone), co-authors J.A. Konrath and Blake Crouch (Stirred), Daniel M. Annechino (Resuscitation), and Kyle Mills (The Immortalists), will all be publishing new titles through Thomas & Mercer in 2011.

That makes five, along with romance imprint ‘Montlake Romance‘, announced on the 4th of May.
