Two Book reviews: Gods of Mars is out of this world and Magic of Oz is magical

I guys. I got two books that I'm reviewing today. They're a little older than what you might be used to, but if you enjoy reading you won't care. The first is the second book chronicling adventures on Barsoom, The Gods of Mars:

Rating: Four out of Five stars
Story:
John Carter finds himself back on Barsoom/Mars, except he's come to a heavily forested area. He meets up with the Green Martian Tars Tarkas while fighting off plant men and white apes. John learns he is in the valley Dor, which lies at the end of the river Iss, which all Barsoomians make a trip down when they are ready to die. While fighting his way through John learns of the mysterious but dangerous Therns, while encountering their enemies the Black Martians. Along the way John learns the truth surrounding the religion and superstitions of Barsoom and must expose it before it takes away everything from him.
Edgar Rice Burroughs is always creative with his adventures and his stories. I like how he used religion as a theme in this book and the warning of how people can use ideas and beliefs to manipulate others. It is not meant to demote religion, but to warn that people will try to use it to hide evil intentions. Racism is used as a tool to show the pride of various Martian races. Readers will find themselves with John Carter on a while roller coaster ride.
Caution:
It is mentioned that Barsoomians don't wear clothes, but that is not focused on. Characters are in constant peril. Some Martian races are described as being cannibals. Monsters attack several people, which may scare some readers.
Lessons:
We should not esteem ourselves as better than others. If we give in to pride, it will prove to be our ruin. We shouldn't be close-minded to new ideas. People may claim to have good intentions when they are hiding sinister purposes.

The next book to be reviewed today is The Magic of Oz:

Rating: Five out of Five stars
Story:
Excitement is in the Land of Oz as Dorothy and her many friends are getting ready to celebrate Ozma's birthday. However unknown to them in a corner of Munchkinland a Hyup boy named Kiki Aru has discovered a magic word that allows him to change his form as well as the forms of others. While flying around the countries that surround the Deadly Desert Kiki encounters Rugeddo, the former Nome King, who makes a deal with him for help to conquer Oz. Meanwhile Dorothy and the Wizard are making plans for a special cake for Ozma while her friends Trot and Cap'n Bill seek another gift. Along the way all parties will encounter unexpected magic and one will be wondering if this will all be fixed before Ozma's birthday.
While not as action packed as most stories, L. Frank Baum has certainly not lost his creativity when dealing with the magical land of Oz. Around the corners are characters and places you wouldn't expect. The magic used in this book is fun, but it is also dangerous as well. Truly reminiscing of the wonders and perils of the classic fairy tales, The Magic of Oz is definitely one for fantasy fans.
Caution:
Characters are transformed into animals, but this is more humorous than scary. A couple of characters are trapped on a magic island.
Lessons:
Wickedness never was happiness. We find greater joy when we help others instead of using them for our selfish gain.
