This certainly had an interesting premise - not just your average 'missing persons' case, the victims here leave only one clue behind, a birthday card that reads "YOUR GIFT IS THE GAME. DARE TO PLAY?" and "HAPPY FIRST BIRTHDAY"
Brought in to investigate the disappearances are Psychologist and Private Detective Dr. Augusta Bloom and her colleague Marcus Jameson (ex MI6). As they get deeper into the mystery and more people go missing it quickly becomes clear that maybe these people aren't under threat, possibly they ARE the Threat. The waters here are very muddy and I did change my mind several times as to what was actually going on.
As for the lead characters, Bloom and Jameson, they worked well together, feeling like a comfy fit. I would definitely like to spend more story time with them and that's not always something you get from these kind of stories. They each bring their own skill sets to the table and what they have complements each other.
I enjoyed this a lot, twisty crime/mystery fiction is 'my thing' and even though it got a bit daft towards the end that didn't spoil what was a gripping read.
Thanks, as always, to Anne Cater for inviting me onto this tour and please, if you get the chance, have a look at the blog posts by the other reviewers on this tour.
