Road to Revenge. Road to..., #1

Rafi only wanted to spend a relaxing day in Tel Aviv with his lover, Mihi.  When a bomb goes off outside the restaurant where they stopped for lunch, killing several people and leaving Mihi in critical condition, Rafi vows to catch the culprits and make them pay. Set on revenge, Rafi accepts an assignment to infiltrate a group of humanitarians to figure out which of them was responsible-and to stop whatever they're planning next.
