Each week the Marvel Unlimited app has a selection of free issues available. Amongst them this week is Young Avengers #9, so if you want to sample an issue before reading the trades, or simply reread, then you have a good chance to do so.
You know, the issue with Prodigy, interdimensional butt-kicking and that ending.
Be warned: This issue may result in tissues.
Also available on the app are some cosmic related issues, featuring the Guardians of the Galaxy and the Silver Surfer. Also, the first issue of Matt Fraction's Defenders run from 2011.
