** spoiler alert ** 
 ***SPOILERS AHEAD*** 
 I agree with the other reviewers that stated that the book, and particularly the epilogue was a giant cop-out on the romance front. From the beginning of the series, the reader was led to believe that Will and Tessa were it, that they were falling in love, and we are never shown that Tessa is feeling the same type of romantic feelings for Jem. Then all of the sudden, in this book, her engagement to Jem is real love and her feelings are actually torn between him and Will? Since when?? When did her feelings of loyalty and even some pity morph into the kind of romantic feelings she felt for Will? 
 Well, I believe since the Will/Tessa vs. Jem/Tessa shippers. Suddenly, to please all her fans, it seems Ms. Clare decided to have Tessa in love with Jem the same she was in love with Will, despite the fact that the previous two books showed absolutely nothing of the kind. 
 Tessa was so wishy-washy and flipped back and forth between pining for both men, conveniently jumping into bed with Will the same night she found out from Will that Jem had "died". And then, when readers finally got what they wished for, when Will and Tessa finally got together (because instead of dying, Jem conveniently became a Silent Brother, something he vowed several times before he would rather DIE than do), all we get is a few sentences about that Will and Tessa were together for a long time, had kids and grandkids, then Will died. 
 Oh and lets not forget that while Tessa was married to Will, she secretly met with Jem once a year on the bridge. Cheap love, much? 
 And the absolute WORST, most selfish part (among all the other selfish things Tessa was and did) was that after Will died, she decided she didn't want to watch their children and grandchildren die before her, so she ABANDONS them. Runs off and leaves everyone. Seriously??? 
 I found that even worse than the fact that Jem has suddenly found a cure at the end, is young again and no longer a Silent Brother, and because Will is now six feet under, Tessa decides since Jem is her other "true love" and she'll be with him now. 
 To me, this totally cheapens the literary romance she had with Will, which I felt had been building from the beginning. Heck, this cheapens the romantic feelings she had with Jem too (which, lets face it, came out of nowhere in this book). It's like she's with one when the other isn't available. I don't think she was good enough for either of the boys, honestly.
