A horrific Kindle perversion
Format: Kindle
Her lines are misrepresented, all left justified. The leading is too large and erratic. The poems run page to page rather than start each on their own. This is a textbook example of a badly done Kindle conversion. Read elsewhere.

Roaring '20's & The Great Depression
Format: Paperback
A great book for an overview of the time period. The illustrations are wonderful and the information gives a good overview to introduce someone to the time period for both children and adults.

A Fun and Wild Ride
Format: Kindle
Two brothers in arms go on amazing adventures, face impossible odds, and grow in ways they never expected. Down to earth, humble, and relatable characters with a continuously evolving storyline, what more could you ask for? Cool weapons and abilities? Epic battles? Magic? Yeah, it’s got all that too.
This series just became a must read on my LitRPG recommendation list.
