3.5 stars.

Neither Rachel and Liam's world (both the one they left and the one they returned to) not Jane's seemed fully developed so much as lists of relevant details dropped here and there throughout, and I was not super into all the romantic drama which the book even ends on. Of course I loved meeting Jane Austen and her family, and there were hints of interesting ideas regarding time travel/paradox, probability fields, butterfly effect, etc., but I didn't really like or relate to Rachel and her dismissive attitude towards love vs lust that so suddenly flipped, and I also didn't like that Sabina was presented solely as an almost flimsy obstacle to their great love: the archetypical "other woman."
