Kirkus Review described Black Mesa as a "...compact book and a quick read... The ending is a doozy of a cliffhanger, suggesting a fourth book is in the offing.
And, yes, the fourth book appears in the spring entitled,
Decline to Die.
What starts out as a cash deal ends up in the shape of a terrorist's nuclear weapon, but the real enemy is cloaked in an Iron Curtain sown tight during the Cold War.
Robbers plunder the Red Cross; Twitter brands them "vampires." YouTube labels the dying, "zombies," and Talk Radio prophesies The Second Coming.
