I really, really enjoyed Lim's first book, Mercy, and am really looking forward to Exile and Muse (the third book in the series). If you haven't read Mercy yet, I really think you should give it a go. It was - by far - the most angelic book about angels I have read. There have been a lot of angel books in YA as of late, but Mercy takes the cake.

SUMMARY INCLUDES SPOILERS FOR MERCY!
Mercy’s search continues ...
Mercy is an angel with a shattered memory, exiled from heaven for a crime she can’t remember committing.
So when she ‘wakes’ inside the body and life of eighteen-year-old Lela Neill, Mercy has only limited recall of her past life. Her strongest memories are of Ryan, the mortal boy who’d begun to fall for her – and she for him.
Mercy soon discovers that circumstances have forced Lela into waitressing at the Green Lantern, a busy city café frequented by suits, cab drivers, strippers, backpackers and the homeless, while caring for her terminally ill mother.
Just as Mercy is adjusting to Lela’s life, her beloved, Luc, reappears in her dreams, and she begins to glimpse her true nature and true feelings for Ryan. What she does not know is that her attempts to contact Ryan may have explosive consequences for everyone around her.
Meanwhile, ‘the Eight’ — the angelic beings responsible for her banishment — remain determined to keep Mercy and Luc apart, forever …
Oh, and in case you are wondering, this is the Australian cover of the book. I've seen another cover floating about for the US/UK edition - but was less than impressed.
