Action/Adventure Aficionados discussion

I am just finishing up a really great book and was wondering what other similar books are out there that I might like. I thought this might be a creative thread to assist with these kinds of book recommendations.

If you would like book recommendations similar to a book you enjoyed, just list it here and others can make recommendations.

Example:

POST: I really enjoyed Jurassic Park by Michael Crichton

RESPONSE: If you liked Jurassic Park, then you will like In Search of the Lost World by Greig Beck

Sounds easy enough...Looking for some great recommendations

I will start it off with I really liked Ready Player One by Ernest Cline
