Are the following sentences free from errors and naturally looked? Thanks Dear Dr. Sajadi, Thank you for introducing me the useful books! I have learned a lot from them. However, I was familiar with most of the concepts in the first book, "geometry of curves and surfaces", I enjoyed the detailed discussions and the intriguing examples. Now, I am in the middle of the second book, "Riemannian Geometry", and I cannot find any better word than beautiful to describe the book! I am completely free for a month and I wonder if I can start reading "Selected Topics in Convex Geometry" along with "Romanian Geometry" or there is a lot for me to learn before starting this books. Thank you for your time and consideration. Sincerely, Meraj
