How I did it: I read a majority of the books years ago when they were first coming out. I made it up to the fifth book, and when the sixth came out, I just couldn't get into it and ultimately left the series alone. Years passed and I always felt like I should have just read the last two books and finished the whole thing.
Lessons & tips: I would definitely try to read the series all in one go, even if you do have to take breaks every now and again. Just remember that leaving too much time between books and pages often leads to forgetfulness and having to re-read!
Resources: It was just me getting lost in the pages of these amazing books. My resources were my own imagination and my passionate love for reading.
