Gears of Ragnarӧk. The Valhalla Mechanism, #3

Ottilie Kingsford's perception of her world has changed rapidly since Loki and Thor fell into her life. With the nine realms in danger and schemes of vengeful Gods coming to light, she found the adventure she always longed for, but it comes at a price. London is falling beneath the constant waves of chaos. With Ragnar?k raging across the nine realms unchecked and all attempts to stop it a failure, Tillie, Thor, and Loki are facing dangers they never saw coming.
The gears of Ragnar?k keep turning unhindered, but someone is controlling the levers. Tillie promised to spill blood for her gods, and she has her targets in sight. Tillie will knock down the thrones of old gods as retribution for their sins. The nine realms burn to ash as the real monsters reveal themselves. Ragnar?k cannot be stopped, but Tillie will not back down. If it takes her dying breath, the favored will fall.
