This book is too advanced for a beginner and too simple for anyone who is ready for its content. Latvian has a complex grammatical structure that is completely foreign to English speakers and this book makes that structure confusing. Furthermore, there aren't a lot of instantly accessible phrases that beginners would need to know in order to survive. The progression is too quick and can cause frustration.The thing the book is good at is providing cultural information so that a newcomer gets a sense of the place and the people. The book follows a story of Latvian Australians coming to visit relatives and seeing the sights of Latvia and can, from this perspective, provide insight for those who don't know a lot about Latvia.The problem is that there are precious few materials out there to assist one to learn Latvian. If Colloquial Latvian is all you can find, then it is better than nothing. But do not place high hopes on it helping you to conquer Latvian becuase it simply won't.
