Query: E-Book Missing Punctuation

My girlfriend got this book for her kindle. Great book, but reading it out-loud is difficult because of all the typos resulting in missing punctuation. For example, the period between two sentences is missing in one place, but the first word of the second sentence is still capitalized. The errors occur at a rate of about 10 per chapter. It's unforgivable; it's like no one read the e-book version before publishing it.
