The Persistence of Memory Book IV: W.I.S.E. Men by Karen Janowsky

Book 4 in the The Persistence of Memory series

One man shouldn't be alive.
One man shouldn't be in love.
One man shouldn't exist.
None of them wanted to be a superhero.

U.S. Army Lieutenant Kevin Rye is the sole survivor of a missile attack on his helicopter in Somalia. His old friend, Rob Fisher, has created a suit that allows him to function. It gives him superpowers and chronic pain.
Corporal Graham Beech, an uncannily talented, womanizing marksman, has just become a U.S. Army Ranger. His future in the military is bright until he falls in love with his friend, Steven Amato.

They are headed toward a crash collision to stop a terrorist from finding Daniel Hecht, a mythological man who will save the world.

“An immersive and emotive urban fantasy tale. I highly recommend The Persistence of Memory Book 4: W.I.S.E. Men to readers of the existing series and those keen to start.” –Readers Favorite Reviews
