I am contemplating this novel by Michael Muhammad Knight. A portmanteau of taqwa, an Islamic concept of love and fear for Allah, and Hardcore, the punk rock sub-genre. Taqwacore thus refers to a genre of Muslim punk rock, existing only in the novel at the time of its writing, but since emerging as an actual genre.
Now on Amazon.com, I hope it will appear soon in Border.
