Great story on how the team pulls together after New York. You can not fly through a portal with a near death experience like that and have everything be just fine. A problem develops with Tony's heart, not the reactor but the points where it is attached to the heart. Eventually his heart begins to fail and the only solution is a risky surgery. While there are some very good action scenes especially the last few chapters where Tony proves for once and all that he is BAMF even recovering from surgery and J.A.RV.I.S. is so human; this story is primarily about the interaction with the team members as they realize just how import Tony is to all of them. It's about weakness in front of your friends, strengths when pain is all consuming, about trust and how sometimes the best families are the ones we make. The shower scene was just heartbreaking and the weaker Tony became the closer the team becomes. Anyone who has watched someone decline in health will relate to the scenes because they have an amazing grasp of reality. The characters stay true to themselves including when Thor brings back Coulson's last words from Valhalla. I admit to tears on that one.

Spark of Genius (Xander/Harem)

Excellent story definitely NSFW due to harem scenes and snorting liquid through your nose and onto your keyboard during some scenes. Luckily I now protect my keyboard with cling wrap due to this recurring problem. Xander decides to let a little fun into Halloween and goes as the grandson of various characters from the Web comic Girl Genius. Due to his luck and the Spark he ends up being catapulted into the DC universe when the spell ends. Even if you have never read the comic (you should) or heard of steam-punk the author does a good job of filling in the background as the story progresses. And this is Xander so either his luck is beyond excellent or so bad to be unbelievable. This is a story that is hard to describe, there is action, comedy, sex, darkness, power trips, jokes on Batman & Superman, stupidity in politics and so much more. The author does not try and jump in the deep end each character is brought forth and developed properly. Xander is not perfect he makes mistakes sometimes big ones and his morality can be a bit shaky at times but he is trying to make a place for himself and keep his girls (You won't believe who is in his harem) safe. He even manages to corrupt his old universe and the Powers That Be are confused.

The Boy Who Fell (Ben Skywalker/Luna Lovegood)

Great story with an unusual pairing. This is a Harry Potter/Star Wars crossover without Harry who died at the age of 4. In this story the world is a little darker and 16 year old Luna Lovegood lying under the stars wishes for Knight in Shining Armor to save and heal her. Unknowingly her magic is different from others along with the fact that she is force sensitive. Ben Skywalker on a routine flight finds his ship being forcefully dragged to uncharted space and crash lands in a pond next to Luna. Ben is able to contact his father through the force and his family is coming for him. Meanwhile he does what a Jedi does best and protects the innocent while trying to keep Luna out his bed. She confuses, comforts, and heals him as he does with her. Then Voldemort makes the mistake of kidnapping her and almost fatally injuring him. Sadly for Voldemort, Luke Skywalker, Han & Leigh Solo and assorted family members have arrived and Voldemort is about to meet someone who loves taking out Dark Lords. Great story with lots of humor as well as angst. There is mention of rape and torture but nothing too graphic. It is good to read a story where the wizarding world is not putting its future on a child, instead they actively fight back. The battle at Hogwarts is just amazing and Han Solo is so in character. I almost choked laughing at the women drivers comment you will see what I mean.

Broken Chains (Harry/Hermione/Luna)

Broken Chains by Darth Marrs

This is not a usual recommendation because this is a very dark story and normally those are good but not worth rereading. This breaks that pattern in that is both excellent and chilling. Remus is unable to stop Harry from going after Sirius into the veil. He continues to come to the veil everyday for a month just hoping. Then Harry gets thrown back out of the veil and the world is changed forever. When he awakes he is no longer Harry Potter he is the Darth Shaddix, Dark Lord of The Sith. Hermione finds that the only person he cannot attack is her and realizes that it means Harry is still in there. Then Dumbledore once again proving that his arrogance know no bounds attempts to break the mental block to separate the memories. It does not go well and what is left is someone who is a blend of Sith and Champion. He intends to remake the world and with Hermione and Luna (as a seer) at his side stands a good chance of succeeding. There is torture, rape, blood shed, dub con and in some cases gratuitous violence. He is not the Harry Potter they knew he is something else. The characterization is amazingly done, the characters make choices  that while not canon fit what they have become. This is not suitable for young readers and is rated M for the torture, rape and the explicit sex scenes. But if you can handle that it is a wild ride, a very believable story and the perspectives change enough for you to see the worlds reaction to the New Savior.
