It's got a premise that reminds me of something Nicholson Baker would come up with: Fink invents a time machine and travels into the past to visit younger versions of herself to warn herself not to do things that she ended up regretting as an adult. She visits her college-age self and tries to stop her from taking a drug that gives her a bad trip. She tells her high-school-age self not to make out with an unsavory boy. She tries to save her elementary-school-age self from a scary encounter with her mentally ill, violent father when he goes on a rampage with a crowbar. She intervenes dozens of times, but does it do any good? I'll let you read it and decide for yourself.
Unlike Chester 5000-XYV, there's no nudity involved in We Can Fix it!, but it does contain a fair number of scenes in which Fink has sex with herself, and many of the incidents are about Fink's sexual encounters as a teen and young adult. Despite some of the heavy subject matter, Fink tells the story with charm and a light heart and renders it with appealing art.
