Chapter 19:

'Declan delved into his jacket pocket, but instead of pulling out another Dusk Ball, he emerged with what looked like a diary, leather-bound and its pages yellowed.

If Flame hadn’t been so concerned with Litten, he might have said, ''What are you doing?! This isn’t the time for reading! We’re in a battle! ''But whatever Declan was doing, he didn’t mind; it gave him more time to decide on Litten.

Declan gave Flame a confident stare (not that Flame was really paying much attention) before opening up the diary and then throwing it, carelessly, forwards. The diary did not hit the floor, though. It floated in mid-air and doubled in size. Black, tattered, and arcane symbols becoming visible.'
