Be gentle when removing them from the book
Format: Board book, Format: Board book
My kids crazy about this book turning into toys. We are probably going to get the rest in the set. Gently push from the back when removing the pop out pieces to prevent the cardboard from tearing and separating from trying to dig them out. I don’t recommend the child put them together as a few were hard to push the pieces in and we bent a couple. Fine in the end but those aren’t going back into the book. They’ll just be room decor 😂

I Really Enjoyed This
Format: Paperback
I really enjoyed this book. The story is coordinated with Star Wars Vol. 8 Mutiny on Mon Cala and Star Wars Vol. 9 Hope Dies. It is not necessary, but to get a more rich, fuller story, you'll want to read this book first then switch over to those two Star Wars main series volumes. I'm giving this review 5 Stars, but I have to say that I wavered on docking it by one star. I'm not crazy about the art. And, although the story is excellent (and as much as I love a good Vader story), I didn't enjoy it as much as I did those two Star Wars volumes I mentioned above; Volumes 8 & 9, Mutiny at Mon Cala and Hope Dies. Those books are top notch excellent. This book, I'd say, is a notch down, at very, very good. Read it and see what you think. As a whole, I like how Marvel is filling out the years between the original trilogy movies with these stories. This story about the Battle of Mon Cala, over two different series, is fantastic.

A great volume with great Tarkin/Vader relationships
Format: Paperback
I am continuing to enjoy this ongoing series showing Darth Vader shortly after Episode 3. It's cool seeing Mon Cala prior to Imperial control. I like how there's a bit of a tie-in with the ongoing Star Wars comic series. There are also flashbacks to the Clone Wars era. I like this time period. Each jedi that evaded Order 66 is dealing with the new world in a different way. I also really enjoyed seeing a young Ackbar. There are two standalone issues included in this volume. First, there's a story that shows the relationship between Darth Vader and Tarkin developing into what we see in the original trilogy. The other is an Annual written by Chuck Wendig. This shows another interesting Vader/Tarkin dynamic. There are a bunch of great references that I love in this issue! Project Stardust. Geonosis. Krennic. Galen Erso. Overall, it's a really cool tie-in to Rogue One. Yet again, I give this volume of the ongoing Darth Vader: Dark Lord of the Sith a 5/5.

A superb addition to the Marvel Darth Vader canon
Format: Paperback
An almost perfect run of comic books, focused around the Imperial assault on Mon Cala post-Episode III. Many familiar faces are here: Vader, of course; Tarkin; Ackbar; Palpatine; Rogue One’s Admiral Raddus; and many more, including Sith, Jedi, and clones (there’s a nice nod to Order 66). Charles Soule deftly weaves an intriguing narrative, fast-paced but also with plenty of depth. The art is also excellent. In addition to the main stretch of the story, the trade also contains the Darth Vader annual, an outstanding Rogue One story that caps things off nicely. Highly recommended reading for Star Wars fans.

Good for Darth vader fans.
Format: Paperback
This book was amazing. I prefribly like vol.4 more than vol.3. The writers of this book have outdone themselves again, another one of Vaders archaic stories and the book was in perfect condition. I highly recommend it.
