3 stars because it just didn't keep my attention like I'd hoped so. My bad. 
 Not my favorite Tahereh Mafi book ever, but I liked it enough to keep it in my library. Furthermore just didn't grasp me like the Shatter Me series. Perhaps a second reading would help me. 
 But I like this book, nonetheless. I just do not see it as a book or even a novel. I see it as a poetry. I am totally mesmerized by its lyrical tale of love, strength, and friendship. There were times where it made me cry, too. 
 The plot started off strong. Mafi created an intricate and well-developed setting al. Although I felt like I could not connect well with some of her characters. Still, I adore Alice, the protagonist. (I like how that rhymes.) 
 Alice, nourished by experience and pain, comes of age by realizing that magic exists in her and that she herself can use it to help others. Oliver, Alice's friend, dares to defy his own conviction and belief where human friendship is prized and demonstrated. Familial relationships are also examined in touching tenderness. 
 Furthermore is composed of a sad, magical, happy and imaginative story. I like how Mafi wrote it with light intensity even though it's full of adventure and mystery. It is very well written, yes. Accessible to young and old alike, yes. 
 Furthermore pulls you in and wraps around you for a rollercoaster ride that doesn't disappoint. 
 Even though it's built on fantasy it radiates lessons on truthfulness, empathy, family, and hope. Read it for the wondrous storytelling or read it for its deeper meaning. But, for goodness sakes, just read it and then give it to the adult or child sitting next to you.
