This is the sort of sentence I hate the most, but the answer rests with the ending of the sentence. Take the last portion of the sentence "Bryan writes in the introduction" and move it to the front of the sentence. Bryan writes in the introduction: "Ashley Bryan's ABC of African America Poetry honors twenty-five poems and one spiritual, "the root of Black song and poetry." This changes the structure of the sentence to make more sense, but it is still one of those sentences that is difficult to read. It actually rates poorly on the readability scale but it is still grammatically correct. You make the main sentence statement, then breath and finish it off with the note that Bryan wrote this in his introduction.
