As author Bob Mayer wisely put it, writers' first books tend to be blood-lettings.
What that means is writers compose stories about their own lives (memoirs or life stories) - for catharsis, or to just tell their story because they need to tell it. Month by month, I continue to see that everyone wants to write a memoir or life story, even though such things don't sell well and are often written like a diary, not a book. (That said, agents will be hesitant to take on anything that's a tough sell.)

Bottom line: "Personal story is dead," as agent Chip MacGregor said in a previous post. However, if you are determined to write yours, make sure you are reading excellent memoir writing. The three books above seem like a good start.
