I have received a school assignment in which we are supposed to read a (any) biography and, as I've been highly interested in Wellington since reading Bernard Cornwell's Sharpe novels I figured I would ask... Could any of you here from r/Askhistorians point me to a good biography of Arthur Wellesley, up to about 600 pages in length(can't be too long, as there's a deadline). The book should be in English (or Portuguese, but I know that's trickier) and be preferably available in e-book format.

I'm not sure this is the best subreddit to ask this, but it doesn't seem to go directly against the rules so I figured to give it a try. That said don't hesitate in removing this if it's not supposed to be here.
