Book blogs I wouldn't mind making babies with, were such a thing possible:
The Readventurer — Flannery, Tatiana, Catie are like the holy trinity of the GoodReads reviewer community. These ladies know their stuff.
Cuddlebuggery — Kat and Stephanie are two of the sauciest minxes/book reviewers I know. Love their reviews.
The Book Lantern — Vinya, Melanie "The Duck", Cory "The Bloodfiend", Ceilidh, Jillian, and Andrea "The Philosiraptor". These ladies are the Avengers of the YA community. Powerful on their own, pretty damn invincible as a team. Check them out.
...more to come.
