It helps, I think, to have gotten to know Maria Dahvana Headley before tackling Magonia: even in mundane milieus like Twitter, she comes off as thoughtful and poetic. And so is her novel, a tale of a teenage girl who can’t breathe — something like asthma, but worse — and what seems to be a ship in the sky, calling to her. She has a BFF, a lad who won’t dismiss out of hand what everyone else thinks are her hallucinations, and he sticks by her until the day she dies — after which things get complicated. This is a wondrous exercise in world-building, and the protagonist is full of self-doubt, but learns to trust her own judgment. After all, a world new to her is counting on her.
