I am currently reading Nightstalkers by Bob Mayer, a fun read so far.
It tells the story of a team of elite soldiers tasked with keeping the world safe from a technology it doesn’t understand. The team of the Nightstalkers are tasked with keeping some sort of trans-dimensional rifts from opening and when they are opened, they are tasked with containing the rifts and stopping anything that comes through.
It is fun and fluffy military SF. There are four books in the series so far and if they are all as good as this one is then I look forward to reading the rest!
I first found Bob Mayer’s book’s with his Area 51 series of books which ran with the whole “aliens at Roswell” thing to tell tales of humans enslaved by aliens and forced to work for them as the aliens sought to sit out an intergalactic war on earth. He takes the whole Ancient Aliens and just goes to town. It is a fun read, weaving in lots of human mythology over the ages ad telling a tale from Atlantis to the current day. The series is a little uneven and some of the books are better than others but it is a fun ride.
