Accidental detectives Jake and Emma Rand are back in their second adventure. Spring is coming to their home in the shadow of Casper Mountain and Emma can't wait to see tulips and daffodils crowd out the snow that has covered her flower beds all winter. Then the May Day Blizzard hits, trapping the citizens of Casper, Wyoming in their homes, closing roads and shutting down highways out of town.
When murder strikes in spite of the snow, Detective Matt Joyner of the Casper Police Department quickly turns up the heat on his prime suspect - Emma's friend, Kristy Castle! As Casper celebrates the annual Summer Solstice Parade and Rodeo, Jake and Emma fight to prove Kristy's innocence. She's hiding a terrible secret, but is she a killer?
