Cricket fighting is a Chinese pastime with origins dating to the ancient Song dynasty. Like pit bulls or gamecocks, crickets fight to the death under controlled conditions. The action and violence of these spectacles lure hardcore gamblers to secret, high-stakes battles at the edge of the underground.
(your hook starts here)
Gregory K. is the reluctant kingpin of just such a skittering underworld and he wants out. He started as a simple exterminator with a fear of bugs but his failures at work and love drove him to find comfort in corruption. His jilted lover can save him - but she'll need to enlist the help of her stalker to do it and she'll have to extract Gregory from a subterranean lair brimming with infestation.

This isn't a hook. Follow the XYZ formula.
