"The Lost Sanctum (The Last Marines Book 13)"
by William S. Frisbee Jr.
The portal was supposed to lead to salvation. Instead, it's a one-way ticket to hell.
The vanhat have returned, and this time they're unstoppable. As alien horrors swarm through human space, Major Zale Stathis receives intelligence about an ancient "angel" who once saved the Voorga from vanhat extinction.
