The book I read was called The Sorceress and in the London central train station and Dee (who works for the Dark masters) has put monsters at all the train stations and airport and police are checking every car all around the world, tiring to catch them. But a Genii Cucullati (flesh eaters) has spotted them and they started to run. Nicholas throws a bracelet witch turns into mud and the creatures are knocked out. They quickly runaway and meet up with an old friend of Nicholas’ he drives them to his house. On the way they past a lot of monsters that look like humans but are not. Once they get to the house Nicholas tries to contact his wife Perenelle who is trapped on Alcatraz by using an old bit of magic he gets to her. But creatures attack her Nicholas tries to save her by giving her some of his aura but his is to weak then the twins help but suddenly the connection breaks and creatures are all around them using their aura they gave their postion away. Theyquickly set the moat on fire ( they can do this because it is made up of oil and metal ) but dee puts it out then thet quickly get away in the car. They go to a little hut which is near stoneheage.
