This is an excellent guide for learning how to write in Arabic script. It is a short book which skips on most other elements of the language. However, this short (and thus encouraging) book covers the two prevalent forms of Arabic script - naskh and ruq'a, typeset and handwritten forms respectively. All 28 letters of the Arabic alphabet are covered, along with a pronunciation guide and numbers 1 through 10 (which is appropriate given the focus on simply writing/reading).
The guides are very detailed and obvious, giving clear examples of not only what the letters look like, but also how to effectively write them (i.e. where to start, finish, and lift your pen). There is practice space in the book to both trace examples and then practice on your own; however, it is probably a good idea to have your own paper and access to a photocopier if you wish to trace the more complicated symbols more than a couple times.
Presented in a compact and well organized form this book provides an excellent way to learn to read and write Arabic script. I'd highly recommend it for anyone that is looking to polish their skills or learn from scratch. And with practical examples and further practice guides this book will take you well beyond simply writing out the alphabet and numbers.
