Finished The Midnight Star by Marie Lu.
Adelina is queen now and she is not a very good one. She’s skilled at battle but she’s not kind. She’s pretty much all villain now, too; she’s paranoid and away from almost all good influences in her life. (Magiano is still around but she doesn’t trust him at all.)
This book absolutely broke my heart but it’s a worthy ending to a great series. (And they can’t all survive, right? This isn’t Twilight.)
