A sci-fi romance set on Mars, where recent refugees from climate-riven Earth are so strong in the low gravity that they are a mortal accidental risk to Martians. Excellent premise, and the contradictory reactions of the protagonist feel real & difficult. But some of the underlying science is dubious (MW ≠ MWh!!!), the romance had potential but felt a bit weak and the ending used up its momentum too soon. Mammoths!
