Trying to find one I remember. Starts with a human guy who accidentally walks through the major wards to the elven lands, without even noticing them, revealing him to have some special power?? At one point in the story, he is playing teleport tag with the bad guys, at an absurd rate of many teleports per second.
I seem to remember he had an elven lover, but that could be wrong. It is NOT Solitary Arrow.
If anyone can point me in the right direction, I'd appreciate it.
