Well, this was enjoyable in some ways... In others, not so much. 
I think I chose the wrong moment to read this. 

I skimmed A LOT of the first half because the build-up to Gareth and Andrew's relationship was too slow: not enough interactions between them, too much Bliss and outside stuff happening. Also, I didn't like that we only got Gareth's POV later on. 

The one thing I did enjoy was the fact that there was a bit of deviation from the usual "sub in danger" trope I've come to expect from this series. Don't get me wrong, I LOVE that trope, but I appreciated seeing Andrew in a more vulnerable position (and also, I appreciated the realistic way the authors dealt with his grief and how they portrayed it as an "ongoing battle", and not something you can get over as soon as you meet somebody else; so kudos for that).
Leo, as usual, completely owned my heart: he's my favourite. 

All in all, I think I probably should have waited for a better moment to read this; I'm so impatient to reach Dorian's book, but maybe I should just skip ahead to it. We'll see!!
