The second book in the Dragon Lance Legends trilogy is called War of the Twins.
To me it seems like the authors have written themselves into a corner, where the logic of time travel makes the story too convoluted and not interesting enough.
Perhaps science fiction writers are better at integrating time travel into their stories? For me it doesn't work here - I preferred the first trilogy, Dragon Lance Chronicles, which was perhaps simpler and maybe less ambitious, but did what it did better.
Rereading this book now, I think I know why I don't have the third book in this trilogy. This trilogy never really took off for me, and I think I simply didn't buy last book.
