Do you plan on making my following interpretation of Finn’s arc in TRoS clear in your novel?
Even after having learned to stand up for himself and for the cause in the past year, Finn is still heavily attached to Rey, emotionally, to the point where he is so desperate to reveal to her he is Force-sensitive. When he intervenes with her fight with Kylo Ren at the wreckage of the second Death Star, she pushes him away — after this point, he finally lets go of Rey and moves on. The lack of a pay-off of the plot point of him wanting to reveal to Rey he is Force-sensitive symbolizes this change of heart.
