Book One
The Cold Iron War
The Elven Queen is invading London. Only Rye can stop her.
A coven of elvish techno-mages — the vanguard of the Queen's army — is already in the city. If they open a portal between the worlds, the army will flood through in a full-scale invasion.
Rye's long-suppressed moral compass has dragged her across the Gap in pursuit of the techno-mages. But in this strange city, alone and cut off from all that's familiar, her lethal skills are useless — she needs friends and allies. Meanwhile Pete, sacked from the company he founded, starts looking into mysterious cat-nappings, and things get weird. Just don't ask about the pigeons.
