At the end of the (non-canon) novel Star Trek Titan: Sword of Damocles there feels like there is something missing or forgotten.

Near the end Xin Ra-Havreii (the ship's Chief Engineer) is left in the Eye of Erykon to try to stabilise it to allow Commander Vale, Keru, Modan and Troi to escape through the outside barrier whilst Titan was trying to destabilise the eye from without.
Xin is left behind to try to counteract Titans pulse at the end of chapter 14.
'No commander' he said, 'I have to stay with the network'
and then at the end of the page
'Good-bye, Commander,' he said. 'If I never see you again, thank you for calling me Xin.'

The problem here is that:

He is never picked up from the Eye of Erykon, Vale, Veru, Deanna and Modan all manage to escape whilst he continues to stabilise the eye.
This wouldn't be a problem apart from in the following book (which is ST:Destiny: Gods of Night), he is already back on Titan!

Am I missing something here? Did I misread somewhere?

How was he returned to the ship or is it a plot hole?
