You know how hard it is to write a different intro to these new-release roundups every seven days? Just curious.

• From Laurell K. Hamilton comes MICAH, the 12th novel featuring her Anita Blake, vampire hunter character.

• GOOD OMENS was the first collaboration between Neil Gaiman and Terry Pratchett. Released in 1990, it’s proved so popular over the years in mass-market paperback form that it’s being reissued in a hardcover edition.

• MASTERPIECES OF MYSTERY AND THE UNKNOWN collects 28 classic Agatha Christie short stories, including “Three Blind Mice,” “Witness for the Prosecution” and all she penned in the supernatural suspense genre. Love the Saul Bass-esque cover.

• 30 DAYS OF NIGHT: RUMORS OF THE UNDEAD is the first of a series of original novels based upon Steve Niles’ acclaimed comics series about a town overrun by vampirism. This marks Niles’ novel debut (here co-writing with Jeff Mariotte), and based upon his terrific short story in the recent DARK DELICACIES anthology, he should be up to the task.
