Toni Kelner sent this along to the contributors of Many Bloody Returns:

First off is Harriet Klausner's review, which is on B&N.com and elsewhere on the web (http://www.alternative-worlds.com/2007/07/26/many-bloody-returns/):

Many Bloody Returns
Charlaine Harris and Toni L. P. Kelner (Editors)
Ace, Sep 2007, $24.95
ISBN: 97804419015221

These thirteen new vampire tales focus on the theme of birthdays (and many happy returns). Although the theme is incredibly narrow and restrictive, the contributors provide fresh interesting tales with no losers and star some of the more famous series characters; this the collection serves as a great introduction (albeit limited) to heroes of the supernatural. The most innovative entry is “Twilight” by Kelley Armstrong in which she insists a vampire’s birthday is the day they convert as that is a rebirthing. The rest of the stories make for a fun compilation with the lively authors being superstars in the undead realm such as Jim Butcher (with Harry), P.N. Elrod (with Fleming), and Charlaine Harris (with Sookie), etc. Still singing happy birthday thirteen times even too many series favorites can become a bit long in the tooth and difficult to blow out the zillion candles for some of the recipients; this reviewer suggests leisurely enjoying the anthology over a few weeks.

MANY BLOODY RETURNS

This is a must-buy book for genre fans, and a fantastic introduction for new readers to some of the best-known writers in the field, including Harris, Jim Butcher, Tanya Huff, Kelley Armstrong, and P.N. Elrod.

SUMMARY: Thirteen authors have 13 very different takes on birthdays and vampires. Highlights include Harris' "Dracula Night," in which Sookie Stackhouse finds herself the only human in attendance at Dracula's birthday party; Elrod's Jack Flming striking a blow for honest mediums everywhere in "Grave-Robbed,; and Butcher's "It's My Birthday Too," where Harry Dresden finds himself in a sururban mall with a bunch of live-action role players and a few vampires out for revenge--and blood.
