Dead Upon Arrival. A Maddie Swallows Mystery, #2

Flying high in the New Mexican sky has never been more lethal. The biggest hot air balloon festival would have been a vacation if Maddie didn't have to balance her apathetic teenagers, a meddling mother, and act as therapist for a desperate patient. Let alone solve a murder case! When Maddie witnesses someone fall from a hot air balloon, it seems like a tragic accident. But as facts come to light, the police are convinced it's foul play.
And Maddie's friend is to blame. With the remainder of the festival canceled and all attendees required to stay for questioning, Maddie has two days to discover the truth behind the murder and free her friend from suspicion.
