Firestorm

This June:

International Rescue goes where they’ve never gone before.

The forest fire of the century sweeps through the everfree. All attempts to slow or stop the spread is in vain. Celestia, now out of options, utilizes the GDF’s emergency communicator. Can The Tracies stop the spread and save Ponyville? What happens when a spelunking adventure goes wrong for Rainbow and her friends? What about when Scootaloo is trapped in an underwater cave with little air? When a dignitary is kidnapped in the crystal empire, will international rescue be able to beat the clock? When a comet is on a collision course with Equis who will stop the mass extinction event?

As Scott Tracywould say:
Thunderbirds are GO!
