Lots of stories for bedtime!
With the changes we all have gone through and that I have not been able to visit my grandson who lives in another State, we have come up with bedtime story Time! It is wonderful! This is one of the books I got for him because he loves his Spider-Man! The book is great, it has short enough stories that are easy to read to a 3 year old and has very bright and well done pictures (which I might add he tells me who these characters are!) I will be able to read to him out of this book for a few nights for sure. I have not bought many books, but do believe this one is very well made. It will be a great addition to his collection when I can finally give it to him.

A great collection, but fails to cast Black Panther as a superhero
There are some great things about this collection of stories: women are well represented in lead roles; backstories for Miles Morales, Steve Rogers, Carol Danvers, and Tony Stark; stories that incorporate Black men as role models; and the important role technology plays in many of the stories.
Now for our big disappointment. The Black Panther story is not about T'Challa becoming Black Panther, but more about Spider Man fighting Kraven, and once disarmed, Black Panther making him, "pay for the crimes [he has] committed against the animal kingdom," by delivering "the final blow." This did not sound like superhero/ role model behavior to us. I also found it strange that all the background characters in this story were white. That is not the New York city I know.
The stories included are:
- Miles Morales as the black spider man
- Gamora vs. Nebula
- Steve Rogers becoming Captain America
- Spider-Man finding his place among heroes
- Black Widow and Hawkeye
- Carol Danvers becoming Captain Marvel
- Rocket, Groot and technology
- Captain America vs. M.O.D.O.K.
- Tony Stark becoming Captain America
- Spider-Man and Black Panther vs Kraven
- Drax, girlfriend Kaz, and Star-Lord
- Captain America and Iron Man seek help of Captain Marvel
Overall, my son enjoys reading these stories and looking at the pictures. Though we will need to continue our search for a good Black Panther story, we are glad we bought this collection of stories, with the Miles Morales becoming Spider-Man story my son's new favorite.
