This book is really good and nicely lays out all the letters in easy to digest chunks. Good written explanation of things with lots of examples. However, there are several editing errors I've found through just the first 56 pages. But in some ways it's good if you can spot them because it just shows you are understanding the material. Also, their are some parts that go unexplained but you just roll with it and it doesn't stop you from learning to write. Some of the examples are in too small of font. If you are looking for a good intro to reading and writing Arabic to establish a foundation I recommend it.
