Siege and storm by Leigh Bardugo *contains spoilers *

Im really enjoying this book. Its the second book in the grisha trilogy.
Reading them back to back has blended them for me a little but having been caught again by the darkling and he sets across the fold looking for the second amplifier from the sea whip to go with the one from the stag. Stormhund was working against the darkling all along and took Alina and Mal back to Ravka to try and help say the city and get the throne back. Stormhund qas in disguise as a captain but really is the prince to ravka and wants the throne instead of his brother having it. So they are trying to find a way to get him to step down.

So much has happened all at once at the end im trying to wrap my head around it.
Nicoklai and alina were working together to try and get the third amplifier.. his brother Vasily  (sp) walked into a trap and the darklong found the little palace and raided them. Not sure at this point how many made it or died.. mal made it and alina but she tried to kill the darkling and the connection which would have killed her too but mal stopped her and they (her, him, and the twins) ran to the tunnels. Where the apparate (sp) has a seceret cave place they are hiding out in.. the end. Lol til book three. But she lost her powers and she is out for revenge.
