Why this must be read:

Summary: Left for dead after a battle, Sideswipe is taken in by the Decepticons, but his thoughts still linger around one of the Autobots.

The Shattered Glass universe is lovingly portrayed in all its twisted glory: the evil Autobots are particularly evil, the noble Decepticons practically out-Optimus G1!Optimus Prime. It starts out a little slow but it goes galloping along soon enough: betrayal! angst! horror! torture! death!

(For those unfamiliar with Transformers backstory, Sideswipe and Sunstreaker are twins, so the implied pairing could technically be considered incest...)
