| I read several of Dan’s books before Da Vinci Code made him a household name. Many of his books follow the same formula, but it it’s a formula that works well for for him. Though this was probably my least of his books it was still enjoyable. Full of the mysteries and chilling action you come to expect from Dan Brown. Susan is a brilliant mathematician but that automatically makes her nerdy and plain to herself and everyone except the one man she ends up entangled with in this book.this is a part of the formula I can do without. Brilliant women can be beautiful too.
