I will take the opposing stance.
Of the list, I only read the Children of Time book and it honestly put me off. I found the writing too dry, the characters too unexplored and the narrative too rushed. Stuff was happening at such a fast pace that it was unclear how characters were (emotionally) reacting to it. I found the generational stories particularly off putting, each chapter felt more like a list of facts than a novel. On the other hand, the book was definitely physically long enough, so I wouldn’t want more padding.
After than, I gave up in the whole author.
