A routine ferry trip across the English Channel turns into a horrific ordeal when the vessel suddenly sinks, killing hundreds. The world is shocked to learn the cause of this disaster . . . a Mosasaurus! Fifty feet long, it was the apex predator of the ocean millions of years ago before supposedly going extinct.
Now it’s back, and ravenous.
Jack and Karen Rastun and their team of elite cryptid hunters from the FUBI join forces with the Royal Navy to hunt down the creature. As more ships are attacked and conventional means fail, the Rastuns come up with a desperate plan to stop this deadly relic of the past. But standing in their way are a naval officer with a personal agenda, a literal ticking time bomb below the waves, and a multi-billionaire who will do all he can to save the Mosasaurus . . . including waging war on the FUBI.
