Have You Seen This Book?

Okay readers, I have a challenge for you. One that I don't hold out much hope for you solving.

Basically, there is a book from my childhood that I vaguely remember, but do not know the title or author. So, I am going to put a list of details below. If you think you know the book, let me know in the comments.

1. Set in modern day.
2. The last event in the book/series is a retelling of Ragnarok.
3. Main character is an original character.
4. Many side characters are taken from Norse mythology.
5. Loki is key, obviously, and there is a detailed description of his imprisonment.
6. It is probably from the children's fiction area (ages 8-12).
7. I owned the book about eight years ago, and I think it had been released fairly recently.
8. May also have been the last book in a series.
9. I think there is a plot point that it is all a video game, or virtual reality (this is uncertain).
10. An earlier book in the series took inspiration from the Greek Minotaur and labyrinth myth.

That's about all I remember. It isn't Percy Jackson, Ragnarok, Rune Marks, The Gospel of Loki or American Gods; before anyone suggests those.

Please if you have an inclining drop a comment below, it's really bugging me I can't remember the book.

Hyper Japan 2014

Panic stations, Hyper Japan is just around the corner!

'What's the problem? That sounds amazing.' I hear you cry.

Well, yes it is but I have a rather pressing issue ahead of me as a result. No, I haven't forgot to order tickets and it isn't fully booked.

My problem, is what to cosplay as. I have some ideas but all of them come with their own hurdles. Dear reader I beseech your advice, but first here are some guidelines.

                                                  I Have cosplayed before as:

I'm the one on the right, I think.

• Dr. Horrible from Dr. Horrible's Sing Along Blog
• The Joker from the Death of the Family arc
• L from Deathnote

I don't want to repeat myself. Also as it's Hyper Japan only L really fits the theme. My girlfriend has decided to go as Ponyo, however we are not couple cosplaying. So don't suggest that please.

I have had a few ideas so far:

Me as L who hasn't done his washing.

1. Sora or Riku from KingdomHearts.                                                                                                
2. Oliver from Ni No Kuni.                                                                                                     
3. Professor Layton from the Professor Layton series.                                                               
4. Lloyd from Tales of Symphonia.                                                                                         
5. Wizardmon from Digimon.

That's all I have so far, I'll post a picture of myself below. I'm open to any and all suggests, but remember time is a constraint and money is tight.

Please suggest away in the comments below.
