The Mystery of the Hot Air Balloon
Oasis Audio ● The Boxcar Children Mysteries
The Aldens are so excited when they get to meet other ballonists, learn how hot air balloons work, and even help the crew launch a balloon. Then, things start to go wrong. Someone is trying to ruin the rally, and the Boxcar Children might not get the chance to ride in a hot air balloon after all - unless they solve the mystery in time.
