This one's in the horror genre but it sounds fun to a Trek fan like myself! Night of the Living Trekkies by Kevin Anderson and Sam Stall will be published on 14 July in the UK.
Synopsis: Our story follows a rag-tag group of Trekkies en route to an annual Star Trek convention. Arriving with homemade uniforms, glued-on prosthetics, and plastic phasers, these fanboys know more than any rational adult should know about Kirk, Spock, Next Generation, particle physics, black holes, and Ricardo Montalban. But when aliens release a zombie plague upon the Earth, all of this Starfleet training suddenly becomes a lot more relevant. Our fanboys find themselves trapped in the Botany Bay Hotel and Convention Center - and desperate to escape. Some will be assimilated. Others will summon the courage of their favorite characters and perform brave feats of heroism. And one reluctant fan will discover his inner Trekkie, rise up, and take command of the crew.
