SIREN is a novel about six people from around the world selected by the UN to investigate a strange musical transmission emanating from Neptune's orbit. They're given a spaceship with cutting edge technology, placed into an induced coma, and expected to report back in three years time. But when the awakened crew arrives at the origin of the transmission, their electronics malfunction and they're driven through the Kuiper Belt. With their engines ruined, oxygen supplies dwindling and one of the team members suffering from hypoxia, time is of the essence for the troubled squad. Their situation grows ever more tense when Tommy Fletcher discovers three alien ships watching their every move.
Tommy Fletcher, the protagonist of SIREN, is the resident linguistics expert who over-thinks, second-guesses and has a habit of biting his nails. He may be in his late twenties, but Tommy's ceaseless trepidation makes the rest of the hardened crew feel like he's fragile and witless. Will the chaotic events happening around Tommy break his brittle will, or can he shed his hesitant demeanour and become a hero?
