This book has a great concept. The idea of time travel with the crystal cavern and the millions of different time lines was fantastic! But there was no real character development and no real depth to the story. So much detail and emotion and drama exists in that story that just wasn’t even touched. This could be an epic tale of time travel! It just fell very flat and felt very basic and bland. It read like a first time rough draft attempt at a novel. Dig deep into the romance, develop the characters, really describe the day to day events of their experiences in full color, let us feel like we are there with them. So much time went by, but was glossed over. I’d love to read this re-worked!
