(I hope you've read death note the labb.. of course you did)so if you know Death Note the games by Blaire and Volpes and if you are a fan of Beyond Birthday you should wait for the their fourth notebook.But it's going to be illogical if you don't read the first ones.The 2 girls are friends of mine and that's why they let me read their books before being published. I can't tell you more because I don't actually support spoilers.Really... can't say for sure but I think this one is going to be published in some couple of months.
