Mark Sullivan is the author of eight thrillers, including
PRIVATE GAMES, which he co-wrote with
James Patterson. His latest effort is
ROGUE, a stand-alone novel, and the newest book in the
Private series,
PRIVATE BERLIN, releases on January 29th. Here, Mark offers a touching tribute to his mom, Betty Jane Walker Sullivan, who passed away in October. Betty Jane was passionate about so many things: her family, Christmas, a good laugh --- and, of course, books. In fact, she was reading and telling jokes just hours before her passing. Although she will be missed dearly on this Christmas Day, Mark knows she will be with her family in spirit and eagerly awaiting all the books they will be unwrapping.
