This book has just been released for ordering on bol.com, and the price has gone from the usual 7,99 euro to 10.99 euro.
I picked up mine at a store in Utrecht for 8,95 last friday, so I'd assume it's just bol.
Sadly, there are no stores close-by that carry Trek novels. I did email bol.com, to ask why they suddenly increased the price. Two days before the release it was still at 7,99.
And I'm really bummed out now that you bought it in Utrecht, since my girlfriend was there just yesterday, she could have picked it up for me!!
