For the first half of the book I actually thought/wondered if Sam might be under the umbrella of asexuality which I thought would've been really cool were it so, as we don't often at all have asexual protagonists buuuut yea turns out that wasn't the case unfortunately. I was a bit worried towards the end that with Marx no longer in the picture that Sam and Sadie might get together romantically but I'm so glad they didn't!

Hmmm... I might need to check out 'The Great Believers' too! :O
