This was honestly a brilliant series and I can't believe I waited so long after reading Scarlet to read the rest of the trilogy. Lady Thief picks up right after Scarlet, and Lion Heart picks up a couple months after Lady Thief.
I think the best thing about these two books are the characters. There is a large ensemble of "side" characters that help Scar and Rob along the way and I absolutely adore them all; Winchester, Margaret, Bess, Much, Eleanor, David, Allan, John (Little, not the Prince) and by the end of Lion Heart, pretty much all the Earls. A.K.A THE BEST CAST OF CHARACTERS. Some of them may not be major characters, but A.C. Gaughen does such a wonderful job with them that we know personal bits of information about even the most minor of characters and it really helps in connecting the reader to the characters. Heck, at the end of Lady Thief, I even felt bad for Gisbourne. Honestly, Prince John and de Clare are the only characters that can't be redeemed.
However, the connection that develops between the reader and all the characters is also kind of brutal because Gaughen is not afraid of spilling blood. The ending of Lady Thief was absolutely heart wrenching because of this and I still don't think I'm over it yet. Although there were a lot of realllly sad stuff, I'm also kind of glad that Gaughen went ahead and did this because the best books are the ones that make readers weep, right?
The plot was also very engaging and there was never a dull moment. It was all adventure and action and every scene/moment was meaningful. There's no fluff in this trilogy, folks. Although I do think there was a lot of kissing going on between Scar and Rob in both books, I also ship them so hard so it's alright. I'm also glad there wasn't a love triangle since Scar and Rob are so dedicated to each other and a love triangle just wouldn't make sense. Also, no spoilers, but there are other couples in both books and I SHIP THEM ALL.
The ending of Lady Thief is a cliffhanger, so you definitely want to have Lion Heart on hand right after. The ending of Lion Heart was great and really gives a feeling of content to the readers. I'm glad Gaughen ends the trilogy the way she does.
Scarlet and Robin Hood's story may have come to an end, but their story is one that will stay with me for much longer. :-)
