My favorite books in modern day would be police mysteries. Especially the "time is of the essence" kind. I realized this was one of my favorite thrillers when I read the Jack Reacher series (Gone Tomorrow). I don't like the "one person murdered" books because it revolves around solving one case. I like the "If you don't solve the case soon, more and more people will die to this killer" and it really gets the heart pounding! I can be VERY verbal and commentative when reading (like that annoying movie watcher). My favorite modern day series are Jack Reacher series and Virgil Flowers Series.
Medieval, I love my fantasy, but especially love my mercenaries or traveler characters. My favorite series for medieval days are the Riyria Chronicles.
My favorite goal keeper would be Goodread's yearly reading challenge. I've gone up at least one book a year. This year, I've set a special challenge to finish the book I start (no matter how bad it is). So far this is my 4th book out of 10
