Anabranch, the sequel to Andrew Zawacki’s critically acclaimed By Reason of Breakings, is a record of philosophical movement into the world, a meditation upon its shadowy routes, and a requiem for what is lost along the way.

Poems in Anabranch have been awarded both the 2002 Alice Fay Di Castagnola Award and the 2002 Cecil Hemley Memorial Award by the Poetry Society of America.
