Nightfall. Shannon Messenger. 2020.

Sophie Foster is struggling. But she knows one thing: she will not be defeated.

The Neverseen have had their victories - but the battle is far from over. It’s time to change tactics. Re-examine everything. Maybe even time for Sophie to trust her enemies.

All paths lead to Nightfall - an ominous door to an even more ominous place - and Sophie and her friends strike a dangerous bargain to get there. But nothing can prepare them for what they discover. The problems they’re facing stretch deep into their history, and with time running out, Sophie and her allies must join forces in ways they never have before.

Sophie must uncover the truth about the Lost Cities’ insidious past, before it repeats itself and changes reality forever.
