In the canton of Yarrowdale, at the very edge of the Empire's reach, an impossible crime has occurred. A Treasury officer has disappeared into thin air-somehow abducted from his quarters while the door and windows remained locked from the inside, in a building whose entrances and exits are all under constant guard. To solve the case, the Empire calls on its most brilliant and mercurial investigator, the great Ana Dolabra. At her side, as always, is her bemused assistant Dinios Kol. Before long, Ana's discovered that they're not investigating a disappearance, but a murder-and that the killing was just the first chess move by a thief who seems to be able to pass through warded doors like a ghost, and who can predict every one of Ana's moves as though they can see the future. Worse still, the killer seems to be targeting the high-security compound known as the Shroud. Here, the Empire's most brilliant minds dissect fallen Titans to harness the volatile magic found in their blood. Should it fall, the destruction will be terrible indeed--and the Empire itself will grind to a halt, robbed of the magic that allows its wheels of power to turn. Din has seen Ana solve impossible cases before. But this time, with the stakes higher than ever and Ana seemingly a step behind their adversary at every turn, he fears that his brilliant superior has met an enemy she can't defeat.

Neil Josten is out of time. He knew when he came to PSU he wouldn't survive the year, but with his death right around the corner he's got more reasons than ever to live. Befriending the Foxes was inadvisable. Kissing one is unthinkable. Neil should know better than to get involved with anyone this close to the end, but Andrew's never been the easiest person to walk away from. If they both say it doesn't mean anything, maybe Neil won't regret losing it, but the one person Neil can't lie to is himself. He's got promises to keep and a team to get to championships if he can just outrun Riko a little longer, but Riko's not the only monster in Neil's life. The truth might get them all killed—or be Neil's one shot at getting out of this alive.

She's got five. But every city also has a dark side. A roiling, ancient evil stirs beneath the earth, threatening to destroy the city and her five protectors unless they can come together and stop it once and for all.
