Eyewear Publishing in the UK will be bringing out an anthology later this year called The Poet's Quest for God. It promises to be a fascinating book not just because of the quality and number of poets included but also because the editorial line has been to include poets of all faiths and none, so agnostics and atheists rub shoulders with the true believers. So far as I am aware no previous anthology has done this so kudos to them.
They are currently running a crowd funding campaign at WeFund. Donations of £15 or more get you a copy of the book, a nice discount on the £19.99 cover price.
