Interested in:

Thor (pre-Aaron)

Black Bolt

Sentry

those are the specifics but anything that's good, I'll read.

Read the Straczynski run on Thor, it´s great.

I don´t know much about Black Bolt

If you want to read a good Sentry story go and check the first issues of Bendis in New Avengers, there is a whole arc about him, I don´t remember the exact issues but it is on the first 20 issues.

Ultimate Spider-man is also great, the best Spiderman run. Also check the Matt Fraction run on Iron Man.

I honestly haven't read much Thor, so I couldn't say.

If you haven't already, you should check out Bendis's New Avengers: Illuminati and Hickman's Infinity and New Avengers for Black Bolt.

For Sentry, you should read Bendis's New Avengers, Dark Avengers, and Siege.

Hope this helps.

The Straczynski run on Thor is one of my personal favourite Thor stories as it was my introduction to the character along with being one of the best runs on Thor to date. I can't recommend that enough. And obviously Walt Simonson's run deserves a mention too. Just read The Ballad of Beta Ray Bill and that was a glorious beginning to his run.

Thor : Blood and Thunder, The Mighty Thor v2, The Surtur Saga

Black Bolt : Silent War, Inhumans ( Marvel Knights),

Sentry : New Avengers v1 3rd arc i guess , The Sentry v1
