It took me a little bit to get the feel of this story - it's slight crackiness sneaked in and I wasn't sure how far it was going, but then I got into the groove and just rocked along having the most wonderful time.
Draco's somewhat manic, hyper-protective, edgy snark was delightful. Poor Harry, with his lousy wife and kink induced impotence was almost pitiable, except he really did want to work out his life. Yaye for Malfoy pointing cock!compass leading him back in the right direction.
Al and Scorpius were truly adorable - and a lovely, crafty, quirky backdrop to Harry and Draco's perambulations. I could see real shades of Marauders style cunning and creativity there - something that was sadly missing from Harry's canon role and most fanfic.
And a great resolution - what a fantastic negotiation and outcome! Really enjoyed this work. :D
