This book made me very, very angry. I'm giving it 2 stars because I did enjoy both the writing style and the premise (although the author does nothing new with it: Emma is just a modern day Dorothy learning there's no place like home).
But the author uses that premise and style to tell a story that doesn't need retelling because it's been told every day, to every woman, since the beginning of time: Everything is your fault. You are responsible not only for your own happiness, but for the happiness of everyone around you. Accept what life gives you, because to want more is selfish. No matter how objectively terrible your life is, this book says, the alternative is worse, not better - never better. As Emmas's wishes go wrong, she tells herself that her old life "will be just fine, because the alternative is unacceptable." Bear your crosses, women, and don't dare ask for more.
*Minor spoilers*
Emma's life is objectively difficult. She works a terrible job to support her unambitious "author" husband; caring for a severely disabled son is both stressful and expensive; she is desperately trying to save her formerly bright, happy daughter from a terrible relationship. Emma wishes away some horrible things, and not only for herself: rape, the very bad-news boyfriend, her son's debilitating disability. And she is punished for all of it. Then the ultimate betrayal: she is baited into losing everything. This woman loses everything for finally standing up to her abusive ex-husband to protect her daughter. She berates herself for these "selfish" wishes: "But it's my fault. I'm the one who took everything away. . . . I was given powers and I abused them." Yes, Emma is the abuser, not her violent ex-husband!
In the midst of this chaos, there is an absurd scene in which Emma decides that in her original life - on top of everything else she is responsible for - if she had just made pancakes for her family more often, they would have been happier. I had to double-check that this author is a woman!
A half-hearted attempt is made to tie Emma's experience to a minor character who may or may not have some type of supernatural abilities. This character is never fleshed out, and no explanation is ever given. Frankly, more exploration of this would have made a better book.
The worst part, I think, is that I don't believe the author actually intended the story to come across this way at all. In the end, it's a mundane "be grateful" parable. If it were intentional, it could simply be blamed on one bad author. Instead, a perfectly well-meaning - and good! - writer reminds us that this kind of thinking is still so pervasive, and still internalized by so many women, that it can unintentionally infect an entire book.
