Won Park has some amazing origami models, I've been following his work for some time. There are a couple models beginners should be able to work through, but most of the designs are geared towards experienced folders. Either way, the included practice currency is a fantastic addition--no more trekking to the bank in search of fresh $1 bills before you begin!
One thing that has to be called out: This book has TEN (10) models, not 15, as Amazon is showing. Look closely at the cover to confirm. The models are: Double crane, crab, camera, butterfly, frog, penguin, eagle, shark, scorpion, and koi fish.
The diagrams and written instructions are some of the clearest I've seen in an instructional book; eager, patient beginners will be thrilled.
Would I recommend the book? Absolutely. This is great as a gift, or a great addition for an enthusiast's collection. If you've been longing to see more of Won's unique designs, you might be a little disappointed, but great content overall.
And Amazon, for crying out loud, please fix the title!
