John Townsend 
Strangers on a Plane [PDF ebook] 

Not long into the flight on a crowded plane Toby gets a text from Todd, a fellow passenger. Todd is carrying a bag with something extremely dangerous hidden in it — but Todd doesn’t know what it is, how it will be used or who will use it. But he needs Toby’s help. Now. This book is part of the Breakouts series. It is perfect for readers who have gained a bit more confidence in reading and who are after a more challenging read, but who aren’t yet ready for longer, more demanding reads.
