Surprised Zaresh didn't mention these;
Earth 132 A series of interconnected stories that has a basis in the main comics canon, but with a number of notable differences. Very Jason centric, but also includes the wider DCU as well. Canonical shippings.
When Sanity Runs Out Roy and Jason, while Starfire is off looking at something else, touch something they shouldn't have and get dragged into Star Wars the Clone Wars series. From there, they run into the clone army, a Jedi with a propensity for one-liners, the Council that promises to help them how they can to get home, an up and coming dual-wielding Padawan, a Jedi Knight inching closer to the Dark Side, war, politics, and a secret plot. A good read, and canonical shippings.
Red X A series of stories that explore the mystery of the second Red X if he were Jason Todd. From the time he steals the suit, to his ventures away from the Titans. It borrows a bit from cannon, as well as from things that should have occurred in cannon, but never did.
