A sci-fi convention gets a dose of true crime in this Edgar Award-winning mystery by the New York Times bestselling author of the Ballad novels.

When Virginia Tech professor James Owen Mega wrote a fictional account of his real-life research, he hardly expected it to get published. But when a publisher changed the title of his novel to Bimbos of the Death Sun, James—under the pen name Jay Omega—becomes an overnight sci-fi star. Invited to the annual fan convention Rubicon, James is both a fish out of water and a Guest of Honor among the Trekkies and sword-wielding cosplayers. But he's not the only VIP at the overrun hotel.

Revered fantasy author Appin Dungannon never misses a Rubicon—or a chance to belittle his legions of devotees. But when Dungannon turns up dead, police wonder if a die-hard fan finally turned to murder. As the list of suspects grows and hucksters hunt for the victim's autograph, James devises an ingenious way to catch a killer.
