Fortunately, this story has a happy ending (unlike the books to which I have been referring.) Because, as I contemplated my case of reader's block, I realized that I have been writing for a blog that reviews books, and therefore, obviously, if I want something good to read, I should simply search 3 Evil Cousins until I find something with a good review, and dash off to the library to check it out. Wow. The solution was staring me in the face the whole time.
So thank you, my dear fellow reviewers, for averting a potentially bad case of reader's block.
Unfortunately, though, this method will not actually help me find new books to review. I must persevere in wading through shelves of sob stories in search of a good one.
