Slash Voldemort/Harry

OMG I think I am in shock this was one hell of a story. Awesome story with the pairing of Harry/Voldemort but be warned this story is not for the faint of heart. The author takes great delight in throwing poor Harry into the deep end. Every time something good happens something terrible offsets it. Dumbledore reaches new levels of villainy but not in a way that is over the top. Harry on his 14th birthday comes into his dragon ancestry in the process killing his family and burning the place to the ground. This sends him on a long road of multiple identities that take him to the dark side. While some may be squicked at the idea of a fourteen year old Harry and Voldemort I am happy to say that due to a misplaced killing curse, a time turner and some electric powers there is an involuntary time travel where Harry didn't physically age but lived 37 years in the past. Yay fiction time travel is always a nice way to fix that pesky age difference. There is drama, romance,  dark humor with plenty of angst and torture. You get to see a new side to the Malfoy family and motherly sadistic Bella is hilariously terrifying. But Harry eventually gets his happy ever after, a little broken, a lot darker, but finally a family of his own with good friends.

Great story, very dark in parts including rape but overall great. Xander has a dark past and to deal with his life he turns to cutting one day he goes too far, luckily he is found by Spike and thus begins an interesting relationship. Spike has always said he is a fool for love and he wants to be needed. The others gradually come around because they see that Spike is good for him. This story features a strong Xander who finally realizes that he is a victim through no fault of his own and most important he is a survivor. The story does a great job of depicting the effects that the abuse and rape has on the friends and boyfriend of the victim. Of course in this case the boyfriend is a vampire and the friends are a slayer, a watcher/mage, and a couple of witches. They get revenge and Xander gets his happy ever after.

Dark Repercussions (Harry/Many)

Great, great story on what happens when Harry is pushed too far.  This is a dark Harry Potter story full of torture, rape, mutilation, angst, drama and surprisingly humor as well. After 5th year the assasain Sang Lys is created and he goes on to collect others for his team. I won't give out names but a few will shock you. The story is well paced and the characterization is interesting. While the characters are very different from canon they are believable and there are no sudden jumps in their development something I detest. You need to go into this story understanding that Harry is fundamentally insane. My only complaint with the story and with all the author's stories is the spelling. While there are some errors due to the fact the author is English most seem to be auto correct giving the wrong word. The author needs a better beta to catch the problems as there is something in every chapter. Other then that which is ignorable the author has done a great job.
