So this is awkward. I published my first book in the Adventures of Caitlin and Rio series, The Lost Colors. Amazon automatically searches for authors of the same name, and assumes that if you have the same name, you must be the same person. It turns out there is another Sally Alexander out there. It is not immediately intuitive but I was able to contact Amazon's Author Central, identify the book by the other Sally Alexander, and request that the book not be associated under my bibliography. I do hope that Amazon can fix this. I feel awkward and uncomfortable having other people's work attributed to me. 

Fingers crossed.
