I can't tell you how much I loved this series. The evolution of Mera throughout the series is an important factor in why. From page one, book one, her quiet strength was evident. She stood up for herself and others when everyone else would everyone else would falter, and for me, there's nothing better than an understated, badass FMC.
The imagination shown in this story is phenomenal! And, despite someone's complaint that they didn't understand the library (I mean, how??), the transition between worlds was seemlessly and effortlessly done. Also, Mera and Shadow are couple goals! 😝
