I typically read every book in a detective series, starting with the first one and rarely have I enjoyed all the books in any one series the way I enjoy the Eve Dallas books. Their characters have grown since the first book. J.D. Robb has kept Eve and Roarke focused while unfolding tantalizing bits of their backgrounds in each successive book. Robb has also kept a firm hold on her settings and best of all, you don't know who did it until the very end! Eve battles her personal demons in Purity in Death as well as the criminals and the endings are never sugar coated. I will keep on reading them as long as Robb keeps on writing them!
