Verina (Ver-ree-na) Sardothien is the infamous assassin Celaena Sardothien's twin sister. Both of them were Arobynn Hamel's prodigies, but Verina never quite had the skill that her sister did. She had been devastated when she had heard that Celaena was captured and when she had found out the reason, she had nearly killed Arobynn. She had begged him to save her twin, and he had agreed to save her in three years if Verina replaced her became her replacement and did what he asked of her . A year later, she is given an assignment she never expected, one that might bring the two sisters closer than they'd been in a year.
