I want to recommend an urban fantasy series set in London by Benedict Jacka. I just read the 11th one, Forged, and man, Jacka is showing some serious craft in the way his main character, Alex Verus, has evolved over the series from a minor mage who runs a shop where he sells crystals and crystal balls to tourists to a powerhouse mage who steps easily between real life, the Elsewhere and the Shadow Realms.
This book includes a caper which introduces a new character, an AI with a great voice, an immensely satisfying battle with Alex’s archnemesis that Jacka has been building to since the first book, and a terrific hangten, heartbreaker of an ending. I hope I’ve baited this hook well because Jacka needs more reader love. Have at it.
