Cloak of the Light by Chuck Black
Drew is caught in a world of light - just inches away from the dark
What if...there was a world beyond our vision, a world just fingertips beyond our reach? What if...our world wasn’t beyond their influence?
Tragedy and heartache seem to be waiting for Drew Carter at every turn, but college offers Drew a chance to start over—until an accident during a physics experiment leaves him blind and his genius friend, Benjamin Berg, missing.
As his sight miraculously returns, Drew discovers that the accident has heightened his neuron activity, giving him skills and sight beyond the normal man. When he begins to observe fierce invaders that no one else can see, he questions his own sanity, and so do others. But is he insane or do the invaders truly exist?
With help from Sydney Carlyle, a mysterious and elusive girl who offers encouragement through her faith, Drew searches for his missing friend, Ben, who seems to hold the key to unlocking this mystery. As the dark invaders close in, will he find the truth in time?
