Hostage by Jas T. Ward

Evan O’Brien lived his immortal existence committed to a life of hardcore service to the secret war and army of The Grid. He had zero time for love, an emotion that complicated his control on all aspects of his life. He was determined his heart had no say. And nothing or no one could change that.
Lily Devenmore spent her days working with kids in a job surrounded by books at the library. She lived as loud and as bold as being born to the Grid allowed. As love found her sisters, Lily longed for it too. But she had yet to find a man who wanted her as she was.
That all changed in one day. Not only was she held hostage but Evan also learned his heart had been held for ransom for far too long. Could they rescue each other? With the help of some of your favorite characters from The Everyday Heroes World, they just might.
