Butterfly Betrayal - Ruth J. Hartman - Bog

Their land sits next to a milkweed-covered field, essential for monarchs. If she's unsuccessful in buying it, her precious, winged friends won't survive. When people end up dead on her farmland, Seneca is suspected of murder. What is it about the milkweed field that's worth killing for? And who's the murderer?
