The five previous books in the Immortals series have focused on five immortal brothers. The sixth installment, Joy Nash's The Crossing, focuses one of the side characters from the previous stories. Manannán mac Lir is half-god, half-sidhe, and pretty bored with his immortal life - that is, until he meets the improbably-named Artemis Black, a very unusual witch who has been stealing life essence from various magical villages.

Artemis is on a mission, one she can't reveal to Mac. But Mac just can't leave her alone, knowing that she's in trouble. As Mac and Artemis travel to the depths of the dark world, they have to learn about trust, resourcefulness and immortality.

The Crossing is patchy, with some exciting parts and some dull parts. Mac is supposedly British, but the dialogue is awkward  - he uses English slang ('bloke', calling people 'love') but not always correctly. The 'love' part is completely overdone as well. Mac and Artemis continually escape from almost certain death which gets repetitive, and I wasn't convinced by their romance. This book is probably one to miss.
