Stark and O'Brien5 books in series
The Payback Assignment Publisher's Summary
Morgan Stark is stranded in the Central American nation of Belize after a raid goes wrong. Felicity O'Brien is stranded in the jungle south of Mexico after doing a job for an American client. When these two meet, they learn that they have been double-crossed by the same person: Adrian Seagrave, a ruthless businessman maintaining his respectability by having others do his dirty work.
Morgan and Felicity become friends and partners while following their common enemy's trail. They become even closer when they find they share a peculiar psychic link, allowing them to sense danger approaching themselves or each other. But their extrasensory abilities and fighting skills are tested to their limits against Seagrave's soldiers-for-hire and Monk, his giant simian bodyguard.
After a series of battles from the California coast to the New York Public Library, they must face a final confrontation with Seagrave's army of hired killers in a skyscraper engulfed by flames.
