The Nullification Engine by Scott Marlowe

An infernal engine threatens all life. A sorcerer's apprentice has no idea how to stop it. The Alchemancer series continues. The city of Brighton promises new beginnings for Aaron, Serena, and the taciturn eslar, Ensel Rhe. But, upon their arrival, Aaron and Serena are arrested for their role in the Chaos of a week ago, while Ensel Rhe slips away on business of his own. The pair are allowed to plead their case before the earl himself, after which they are released and assigned a very special duty. The Chaos unearthed an ancient, infernal machine called the Nullification Engine, and the earl wishes to know everything about it. Dormant for hundreds of years, the device is now active and gathering energy for some unknown purpose. While Aaron and Serena struggle to unravel the machine's mysteries, Ensel Rhe confronts his past when he learns his daughter has come to Brighton, but in the company of one of his greatest enemies. A race against time begins as Aaron realizes that the Nullification Engine was never turned on for a reason, for once the machine reaches a state of full nullitivity, it will destroy Brighton and everyone in it.
