Details are a bit sketchy, but the important ground is covered. The author of the book is none other than Michael A. Martin, an old hand at writing Star Trek novels. The title will be "Star Trek Online: The Needs of the Many", it will have 340 pages, and the release date is set for March 30th, 2010.
The actual content of the novel is of course not known yet, but fan speculation has offered up the two obvious ideas: a summary of the years between Nemesis and 2409, or possibly something more specific regarding a significant event within the STO universe. In either case, fans of Michael A. Martin's previous work are sure to view this as great news.
The book can be preordered through Amazon.com now, or directly from the publisher.
