Choose Your Own Adventure #1
R. MontgomeryLaurence Peguy (Illustrator)

You head to the Himalayas in search of the Yeti, otherwise known as the Abominable Snowman. But when your climbing pal Carlos goes missing, your search takes a very different turn. The first fork in the story happens en route to Nepal, when you must decide whether to bail out of a faltering plane or attempt a crash landing. 28 different endings range from pretty bad (you meet a poacher and are thrown into a pit of tigers) to great (you rescue Carlos, doing good deeds along the way, and meet the mysterious Yeti).
