The Melody of Three

Sorcerer Christaan De Rein's return to Liverpool does not go well, starting with the fact that his trusted apprentice, Higgins, dies on the way. Then again, Higgins dies a lot. Of course, Rein doesn't expect to be welcomed with open arms after being banished for nine years, but a cryptic summons from The Musician herself cannot go unanswered. 
 

But when Rein arrives all is in chaos. People with fairy blood are turning up dead. The Forum Magicae is undone and the Curators sieged. 

And in another world altogether, where Earth is just a legend, a girl named Niena and a cursed lyre hold the key to saving both realms. Or destroying them.
