Some novels make a simple promise. This one sounds like it is making several at once, and somehow getting away with it. The Book of Love gives off the kind of energy that suggests grief, magic, teenage intensity, and genuine strangeness all occupying the same room without apologizing.
That is usually a good sign. I trust ambitious fiction more when it seems willing to be emotionally messy and structurally confident at the same time. You do not pick a title like this if you are planning to play timid.
Kelly Link also tends to attract readers who want atmosphere with teeth, not just decorative oddness. That matters. Weird fiction only works when the weirdness feels earned.
If this one lands, it is exactly the sort of book I would want to disappear into for a weekend and come back from slightly altered.
