Don't buy this book. Better sources exist for FREE; search for:
1) ancient-hebrew dot org and you'll find a good site. on the left-hand side will be the menu; scroll down till you see "learn hebrew". "alphabet" and more is available--with audio files--for free.
2) "foundationstone" this is a free downloadable program that teaches hebrew.
3) "hebrew4christians" dot com and you'll have another good source.
4) "learn-hebrew dot co dot il" is a free Hebrew vocabulary website offering 46 topics in over 1700 Hebrew words and phrases. For each word and phrase you can find a transcription & Translation and to hear the right way of saying it.
These sites will not only teach you everything for free that this book instead sells to you but a whole lot more. This book is also over-simplified. It's mostly a waste of time since any adult or child, with the correct motivation, can learn much more than this book offers at a much faster pace. Also, the "script" form of the letters was calligraphed and not practically written for the beginner who wishes to actually write it. "The First Hebrew Primer" gives a much better source with three choices of style available: book print, block print, and script. A student can easily write Hebrew immediately with this book's help. However, make sure whether you're wanting to learn Biblical or Modern Hebrew because pronunciation and other aspects of the language can differ between the two. If you would like two good "modern" Hebrew sources, check out the "Foreign Service Institute Hebrew Basic Course," which you might find for free online. Search for "free fsi-language-courses". The other is, "Colloquial Hebrew: the Complete Course for Beginners" by Lyttleton and Wang you might find extremely useful!
