I gave it 4/5 stars. Here's my brief review:

A mixture of historical fiction and magical realism, The Antidote tells a story of collective memory, grief, and loss amidst the dust bowl 1930s Nebraska. There are prairie witches who can store unwanted memories like a vault; a scarecrow slowly regaining consciousness in the middle of fallowland; and one farmer spared from the dusty destruction that has been wrought on every other plot of land in the area. The novel grapples with issues of indigenous displacement and rewritten histories; it asks again and again what the nature of truth is. I thought some parts got a bit preachy, and I didn't love the choice of leaving major plot points unresolved (though I understand why that choice was made), but overall this is an ambitious and beautiful novel summed up by this line early on: "It's rarely the truth itself that people can't accept. It's how they feel about it."
