Whilst I think this YA was aimed at the lower end of that bracket, and therefore I was not the target audience, I did enjoy this story. In this multiple-perspective story, you follow Tavia and Effie who show that family doesn't need shared blood. Rich with mythology, A song below water introduces sirens, mermaids and more to our world. The ending was a little rushed for me, not giving me the satisfaction I wanted, but the rest of the book more than made up for it. Bonus - I learnt so much about caring for black hair which was a pleasant surprise!
