Samantha Markle did not deliver an insightful book. I found it to be a boring read, mostly because she could not offer anything about herself that is appealing.
The book was empty because she has no relationship with Meghan Markle; she demonstrated in her book that there is no sisterly relationship. It was obvious that she did not know Meghan Markle.
Importantly, Samantha Markle is dry and I suggest readers do not waste 2 hours of their life reading her book.
