Yeppers the Solo family is having a tough time.
CHewy is dead,
Anni is dead as well
One twin (Jacin) is captured
One twin (jaina) flirted with the dark side dealing with rage and the pain of lossing lots of people close to her. Kip (the Jedi at odds with Luke) helped her thru it so she only flirted with the darkside.
The new Jedi order series is quite large with many books some much better than the others.
One character I am hoping they fill out more is Wedges Nephew Fet. He has potential to be quite an interesting side story.
“Rebel Dream” was a so-so book like some of the others in the series, but does fill in the time line for the whole saga nicely.
