Here is where I'm sure a lot of people will unfollow me, but I have read over 300 pages of this mess and I have yet to say "this is everything it was hyped to be". Spoilers ahead.
Jane was endearing at first. Her love of books was sweet. But like I have stated preciously, funny books never seem funny. They end up stupid or obnoxious. Aaaaaand this one did too. What was funny at first became old and nerve-grating. Like the titles of books Jane read. Etheeuhns: Historical Figures and Their Downfall, Wilderness Survival for Courtiers, Herbs and Spices Indigenous to the Spanish Highlands, volume 2, The Proper Treatment of Wounds on the Battlefield During the War of the Roses, a history. There are more but this is a taste. I get that this book is supposed to be in the style of the Princess Bride but it was still obnoxious.
Then there was the overly convenient plot points. Whenever someone needed an escape, a person who previously had no ability to shape shift could suddenly change and run away. It just seemed like weak writing. Again, this is just my opinion.
This book had its moments of humor, but mostly it fell flat and disappointed me.
