The book 'Four' give us an insight into Tobias's life and what happened during his formative years. Veronica Roth has definitely succeeded in introducing a whole new perspective to the series, helping the reader see in-depth how such an innocent boy like Tobias had to battle his past set backs.
This book also gives inside information on how Tobias really felt when he first met Tris- and how things grew from there.
Overall, this book has captured my attention, even though it is a prequel which is always difficult to introduce successfully.
Altogether, Veronica Roth is a great writer with exceptional ability to entice the reader: the whole series was a huge rollercoaster from start to finish. This book is no different-it couldn't have been any better!
Thanks to Emily for such a brilliant review!
