Necronauts

"When the world-famous escapologist Harry Houdini slips into a near-death state while practicing his act, something horrible from the boundaries of consciousness follows him back...

Now Houdini must join forces with the era's most famous aficionados of the uncanny — Sir Arthur Conan Doyle, Charles Fort and H. P. Lovecraft — and try to defeat an evil force which wants to enslave the human race.

''However, this intrepid group must not only face the enemy's terrifying agents of Earth, but also a traitor in their midst. Not to mention the dire, eldritch horrors which lurk just beyond the veil of sanity..."''1
